I anxiously awaited this summer 2010 update to the iMac line.

iMacs offer a better value than one might think, and the space saving they offer compared to having many components spread out on a desk, make them an attractive offering from Apple.

My current iMac was an aging model, summer 2007. The first iMac with aluminum enclosure. Honestly, however, it is not far off the machines of today particularly notebook models. The iMacs are aging nicely, and I'm sure this new model will too. iMacs tend to offer a better value than notebooks and because they aren't carried around, can have better reliability / longevity too.

When I opened this new computer, I loved the widescreen display. This display is 16x9 similar to a television, whereas conventional widescreen computer monitors were 16x10 (including my old iMac). The extra width gives you more room to fit documents across your desktop (screen) while working. I like that.

Furthermore, don't let anyone suggest that this is not a fast computer. Its 3.2 GHZ i3 processor includes hyper threading to give you up to four "virtual," cores. Some argue that this feature isn't useful, or that not enough applications utilize hyper threading. However, I was able to look at CPU usage and see video encoding software on my computer using the multiple threads. It was fast.

I chose the 21.5 inch model because my desk is simply too small to house the 27-inch model. The 27 is absolutely staggering in size. I would choose it, if I had the room, but the 21.5 is far from being a slouch and is somewhat more sensible looking.

It features standard 4GB of memory, which can be easily upgraded to 8GB by buying two additional 2GB sticks.

I'm 50 years old and have been using PCs all adult life for work and home. I've had what I consider to be very good PCs & Laptops over the years. I NEVER thought I would switch over to a Mac because I'm not into gaming and I'm not an artist. But I just made the switch and I'm thrilled, to say the least!

The analogy that comes to mind between the two is this...
I liken my current (and past) excellent quality, loaded Laptop PC to a strong, healthy work horse. It looks nice, it feels and looks strong, and I have no doublt it can get the job done. We have a good relationship, we're buddies.

But I liken the iMac to an Arabian stallion! It's simply gorgeous to look at and touch, it's muscles are rippling and glistening with strength- it has unfettered energy, and it can take me places I can't even imagine right now! But don't get me wrong... if there was crap behind the screen and inside the housing, no amount of good looks could make up for it. What I'm really falling in love with is the way it thinks, the way it works, and the possibilities ahead of me. It will do the mundane work that I need to get done, with a style, flair and ease that the PCs just don't contain and it's making my work feel not so much like work anymore but like play, and I know it's going to inspire me to be more creative with the work I do and the projects I'm just starting to envision.

Regarding Customer Service; I don't care how good customer service has ever been with HP, or Dell, or any other brand that I owned, Apple's customer service is in a different league with or without their Apple Care plan, which I highly recommend. They are amazingly helpful and personable- as if you're talking to someone you could easily be friends with- any one of them that you speak to. ...

After 25+ years of using PC's (started in the MS DOS days) I got my first Mac, and I love it! Just an FYI, I ordered this model direct from Apple using an education discount, plus upgraded the processor to the dual core i5, but everything else is the same as the model above including screen, GPU, RAM, and Hard drive.

The screen is gorgeous! It has a tiny taint of "discoloration" towards the bottom of the screen (some people have referred to it as yellow), but it doesn't bother me, I hardly notice it all, and I only bring it b/c some hardcore mac users do test after test looking for this "defect". My machine is lighting fast, and ultra quiet. It gets a little hot at the top, but what do you expect for an entire desktop encased in aluminum?

I own an iphone and an iPad, but as a new mac user this was a breeze to set up. It took me a while to perfect the transfer of my itunes library as I'm very particular about not duplicating files, but now its all set up. I set up a 2nd account for my wife, pulling my media to her itunes as a shared drive system which was much easier than I thought it would be. The iSight camera works great for skype and iChat.

I'm getting used to the keyboard and mouse, but overall I'm very please. I've already used bootcamp to install windows 7 ultimate 64bit, it runs fairly flawlessly. I installed parallels 5 as a virtual machine, it works quiet well, but windows "thinks" the VM is a new computer and asks you to reauthenticate windows and MS Office licenses which is a real pain in the ass. But that's a microsoft problem, not mac.

I haven't had a chance to use the iLife products yet, but I'm looking forward to it. I've started ripping my home DVD collection to iTunes via Hand brake and its super quick and easy.
