I saved more than $500 by purchasing this from Amazon, but it seems that Amazon gets the less than perfect computers. The first to arrive operated beautifully, but had a scratch on the screen. Amazon replaced it for free, but I had to pay more than $100 to ship and insure the returned computer...which will supposedly be reimbursed soon. The second computer has a bit of fuzz behind the lower right corner of the screen, but it's worth keeping it to avoid the return hassle. However, I will have to bring the computer to the Apple store next week so they can fix the loud drive.

This mac is amazing and the 27" screen just makes it better. I upgraded from a iMac G4 and the performance is a huge boost. With a 3.2Ghz processor and 4GB of standard RAM it's one fast computer with lots of capabilities. I would suggest buying it from Apple because it's free shipping and you can customize it beyond what you can believe. I would definitely recommend this to anyone looking for a new computer or upgrading their old mac. The display is so big you have to see it in person. Also, it comes with Boot Camp installed so all you need to run Windows is a disc to install it. Overall a great computer and one I would recommend to someone looking for a computer.

First things first: the iMac offered on this page has the dual-core Intel Core i3 processor. A configuration with a quad-core i5 processor is also sold by Amazon. In addition, an even more powerful quad-core processor, the i7, is available as a build-to-order option from the online Apple Store. Be sure you're looking at the configuration you want. Apple makes four 27" Aluminum iMac processor setups in all: an i3, two with the i5, and an i7 (see the Comments on this review for a link to Apple's official tech specs).


Now then, on with the show. Many reviewers of the previous release of the 27" Aluminum iMac have already discussed the essential hardware and software features. So, rather than repeating stuff that has already been said, I am going to focus this review on my experience of upgrading from a G4 igloo iMac that was running System 10.5.8 .

Migration Assistant
*I used a Firewire 400 to Firewire 800 cable to move the contents of my old computer to the new machine with Migration Assistant.
*The process was virtually seamless, with only a few minor adjustments necessary to the transferred data. Only four applications required reinstallation: ClamXav, iTunes (due to the Soundflower plugin--in any case, no music was lost or damaged), Microsoft Expression Media 2, and a Juniper Networks remote access program (part of a corporate telecommuting package).
*Rules for Little Snitch, a third party utility, need to be reestablished.
*Customized preferences for Spotlight must be reentered.

Magic Mouse
*iMacs now come with a wireless mouse as standard equipment. The Magic Mouse is a vast improvement over the Apple Mouse (aka Mighty Mouse) because it doesn't have a roller ball that eventually stops working. In fact, there aren't any external moving parts on the Magic Mouse, other than the on/off switch.
*Exposé and Dashboard functions are now on the top row of the keyboard, not on mouse buttons.
*If you're interested in the new Magic Trackpad, you'll have to order it separately. It doesn't come as standard equipment right now.

Keyboard
*The chiclet style keys took me a little while to get used to, but now I prefer them to traditional "long stroke" keys.
*For some reason, Apple has made a compact laptop keyboard the standard iMac keyboard (Steve Jobs must be nostalgic for the original 1984 Mac keyboard). Anybody who relies on Page keys for navigation or on a numeric keypad for data entry is out of luck.
*An extended keyboard with Home/Pg Up/Pg Dn/Delete keys and a number pad is available as a build-to-order option, along with additional memory and other treats, at the online Apple Store.

Audio System
*Optical digital audio input and output requires cables or cable adapters with 3.5mm plugs. Standard size TOSLINK connectors won't work. Also, digital audio I/O is run through the microphone and headphone ports. It is consequently impossible to use headphones or an external mic when the computer is setup for optical digital audio use.
*The speakers are a weak point in the design. They are small, underpowered, and sound tinny. I think the igloo iMacs had much better sound. If I recall correctly, they had a specially tuned amplifier--plus the speakers were fairly large and were not built into the computer housing. Users who use their iMac as their main music source or who work with music and sound will want to buy a separate pair of speakers.

Using the computer: screen, fan noise, heat, Rosetta
*This iMac is all about the gigantic 27" screen. It's incredibly sharp and bright, with better-than-HD resolution. Excel users will love being able to see columns A-AE and rows 1-95 all at once at 100% zoom. No more wasting time scrolling around and splitting windows. Photos, movies, and graphics all look absolutely fabulous.
*I initially thought I would hate the glossy finish on the screen, especially after seeing how much glare demo models at the Apple Store showed. But, as it turns out, the shiny glass isn't distracting at all in my home office. That said, anybody who hasn't ever seen a glossy screen computer in person should go check one out before placing an order.
*Something that I miss from my igloo iMac is the ability to move the screen both from left to right (x-axis) and up and down (y-axis). Aluminum iMac screens can only be swiveled up and down, in a fairly limited range.
*Under most conditions, the computer runs very quietly. Fan noise is normally inaudible.
*The top of the computer can become noticeably hot to the touch. Not hot enough to cook the proverbial egg, but definitely warmer than most other electronic devices (except for the original PlayStation3, otherwise known as the Sony Spaceheater).
*PowerPC applications run well under Rosetta. Once it is downloaded automatically, upon demand, it runs invisibly.


Bottom line: it's the screen, the SCREEN, THE SCREEN!! Massive amounts of screen real estate, combined with fast performance, make the 27" Aluminum iMac a true joy to use for both work and play. One star penalty for not making an extended keyboard standard and for the terrible built-in sound system.
