The iMac is  a line of Macintosh desktop personal computers, released by Apple Inc. The features that can be currently found in the Apple's iMac configuration are  Intel Core processors, GeForce nVidia graphic or ATI Radeon High definition  integrated cards. Also, the displays can be either 21,5 inch or 27 LCDs.

Although the elder models of iMac had a polycarbonate white case, the older generation have a shaped and styling enclosure. When you see them you can easily think to Apple's Cinema Displays, a product line of flat widescreen monitors, or to an iPhone. Following the success of the MacBook Pro, the designers used this model of assembly, incorporating in iMac an unibody case. Yet, the elder model of this product, the aluminum one, had a black back, made of plastic.

In a Steve note at the MacWorld conference from January 10, 2006, it was announced that the iMac will be the 1^st MacIntosh that will use and Intel Processor, in a Core Duo system. That was the moment when started a 6 month period of transition between PowerPc and Intel. Since the iMac G5, the only thing that changed was the processor's  speed , the price, the design or the features remaining the same.

The 1^st computers from this line, along with the MacBook Pro, represent the first Apple's computers with an Intel CPU. Since they introduced the iMac Core Duo, and had a real success, the other product lines have adopted this configuration, including the Mini Mac at the start of 2006, the MacBooks at the middle of the same year, followed immediately by Mac Pro, on August, and the Xserve in November.



In February 2006, users reported that the products have some video display problems, like random lines on screen or video bucking.  These major problems have been solved with an immediate software upgrade.

At the end of 2006, Apple Inc. introduced a version of  iMac that had a Core Duo chip inside and a much lower price. Also, they added a 24 inch model that can support a resolution of 1920 x 1200 pixels that stands for widescreen ultra extended graphics array and have a 16:10 screen aspect ratio. That represented the first iMac that could display HDTV video mode, a system that uses full frames just like a jpg picture, in 1080 TV lines of progressive scan. Also, they released  on this product and a VESA mount, a flat display mounting interface. With the exception of the 17 inch model, all the versions included also and a IEEE 802.11n-2009 draft card.

Making a comparison between the early 2006 models, the Intel Core Duo and the Intel Core 2 Duo models, released in the late 2006, we will review the technical configurations and we will figure that there aren't too many differences. They have both an white polycarbonate enclosure and can be found in a 17" 1440 x 900 and 20" 1680 x 1050 matte display form, all wide screen. Yet, the second model can be found also in a 24" 1920 x 1200 variant, also matte.

On the graphic card side we can see a major difference. The first model had an ATI Radeon X1600 graphic, with 128 MB SDRAM, or, as an option, with 256 MB available for the 20" model. The late model have either an Intel GMA 950 with 64 MB memory shared with the main one, either an ATI Radeon X1600, either a nVidia GeForce 7300 GT with 128 MB of GDDR3. The last model it is available and with 256 MB of GDDR3 SDRAM, only for the 24 inch models.

Both use a serial ATA hard drive with 160 GB or 250 GB capacity and 7200 rotations per minute. Optional, the user can acquire a  500 gigabytes one.



The earlier model had an 1,83 GHz Intel Core Duo processor with 2 MB on-chip L2 cache, unlike the younger model  that is an 1,83 GHz T5600 Core 2 Duo for the low-end 17" only, or a 2.0 GHz T7200 for the high- end 17". Optional, you can choose a 2,16 GHz processor or a 2,33 GHz for the 20 inch and 24 inch models.

The Air Port it is integrated in the both models and they are disabled by default. The later model have and a 24x combo drive, available as an optional for the low- end 17" only. Both, the first and the second model have as internal slot- loading an 8x Super Drive with 2.4x double layer recording for DVDs, rewritable DVDs and rewritable CDs.

Steve Jobs introduced in July, 2009, a fully restyle of iMac, providing an aluminum and matte glass design. The only screw that it is visible on this models it is right in front of memory slots and it is made to assure an easy access to them. The back it is now solid and black and it is not anymore removable. They totally removed the 17 inch model and introduced a 24 inch one.

In March, 2009, Apple Inc introduced a brush up to iMac product line with a USB port, a double RAM capacity, a slimmer restyled base and leaving only one FireWire Port.

The MacBook Pro is a line of notebooks released by Apple Corporation at the start of the year 2006 at the Macworld Conference & Expo, in the United States, a special exposition dedicated exclusively to the MacIntosh products, as a replace of PowerBook G4, a notebooks line sold between 2001 and 2006.

MacBook Pro was produced under the MacBook's family range, along with the consumer-focused notebook and the ultra portable thin notebook, MacBook Air , being positioned at the high- end part of this line.

First model of MacBook Pro was a large and heavy notebook, using just like as his second version, aluminum. There are, in this moment, 3 available models of MacBook Pro and they have different measures like 13", 15" and 17" .

The first model, the 13" one,was released on January 10, 2006,  and was criticized because from its components were missing the IEEE 1394 interface and the Separate Video ports. These parts was added on the later models, 15" and 17". Also, this models was upgraded  with a type of webcams, developed by Apple Inc. , both external and internal, named iSight and a MagSafe connector, a connector which is held magnetically in its slot.

The MacBook Pro  Special model  have an impressive configuration which contains a Intel Core 2 Duo processor at 2.5GHz, a 17" display, available in 2 types, mate or glossy, widescreen. It have one of the best graphic cards from the market at this moment, represented by a nVidia Geforce 8600M GT with 512MB of GDDR3 SDRAM . Its hard drive can support almost 5400 rotation per minute  and have a capacity of 320 gigabytes, with a Serial ATA slot.  Contains also and 2 GB RAM memory split in 2 boards.

Like all the models from the MacBook Pro family, this one has the left side of the case shifted and the optical drive slot removed from this part and integrated on the right side. Also,  the DVI, a high-quality video interface for digital displays, was  replaced with a miniaturized version of the standard digital display interface, named Mini Display Port.

The MackBook Pro model is stylish and lightweight, in contrast with its predecessors, using an unibody construction, but deeper and wider thanks to its widescreen. The touchpad was also been enlarged making the scroll and interacting with it, method also known as multi-touch, more easier and attractive. The keyboard is back lighted and arranged in a QWERTY system, the most used keyboard layout in these days. The hard drive is located in the battery compartment at the 15" model and under the bottom panel on the MacBook Pro model, characteristic that makes it irreplaceable, requiring a entirely disassemble of the device.

Its battery also has an unique design because the designers wanted to use all the free space and didn't used the classical round cells inside of it. The material used to create them it is the best from the market, the lithium-ion polymer, used to create rechargeable batteries, that helps to extend the battery's durability. On the experiments it was proofed that the MacBook Pro has an 8 hours life and can be recharged up to 1000 times.

Also, even it is looking perfect, the MacBook Pros have some problems with the wireless connections like the third part routers connectivity. It is loosing frequently the signal and have problems with the IP requiring part. The users, and even the Apple's experts report problems when they tried to access a secure network but the solution of this it will be a simple turning off and on of the AirPort.

To improve the quality of the MacBook Pro, the experts elaborated some solutions for these bugs, but there are pretty hard and uncomfortable like deleting the wireless network and re-make it or rebooting the entire system for one minute.

Even if it has some little problems with these aspects mentioned, the MacBook Pro one of the best notebooks from the market and will let every user perplexed every time he or she will use it. Also, it is impressionable that finally, the Apple Inc. putted a SD Card slot, a massive detachable storage,  in one of its products.

The MacBook family are very popular line and  this high-end product, the MacBook Pro, made on every single user a good impression and never disappointed.
