"A great intro level desktop for people new to Apple"4.0 starson by drahcir1302
Pros: New Thunderbolt Port allows for great, future peripherals. Display is top-quality. New processor is in line with new MacBook Pros
Cons: Can not upgrade the 512 MB graphics card. Thunderbolt peripherals are not easily available (yet!)
Summary: Simply put, if people are looking for a desktop that will introduce the family to Apple computer, or replace the old iMac around the house, this is the right choice. While the hard drive is not as large, and the RAM is not as fast as it's price-equivalent Windows competitors, it is still worth the switch due to the ease of use and stability/security of Mac OS X. Besides, they can easily be upgrade, either through Apple or a third party, or by yourself, as Apple has instructional guides on their websites that make the process very easy.
If you're looking for a professional-grade machine, you may want to look for the $1,999 iMac, which has far more options when it comes to upgrading, most notably, the graphics card. While the 512 MB card that comes installed on this unit is fine for general use, it may not be enough for any hardcore gamer or video/graphical professional.
Apple has also begun shipping the new iMacs with the option of getting their Magic Mouse (a wireless mouse that has a smooth top that the user can swipe their fingers across to create gestures for shortcuts,) or swapping the mouse out for their Magic Trackpad at no extra cost, which functions a lot like a laptops trackpad, but also allows for the gestures that you would use with the Mac OS X operating system.
With Apple's plans of releasing their new operating system update, Mac OS X Lion (10.7), expect this iMac to be the perfect solution for any family's computing needs. Just don't expect to upgrade many of the internal options without stepping up to the 27" iMac.
