I have been a PC guy for most of my life. A couple of years ago (2008), I bought my wife a 20" iMac with the idea that it would be easier for her since she mostly just does email and was always frustrated with her PC. Well, after playing with her iMac for awhile, I bought myself an aluminum unibody Macbook to play with, but still kept the PC as my primary desktop. This year, just after the "new" quad core iMac was introduced, I finally gave up the PC for good and bought an entry-level 27" i5 iMac (1TB, 4GB memory). Because I have so much PC software, I also installed Windows 7 using Bootcamp. My iMac has Snow Leopard (I got my system about 2 weeks before Lion. I have no immediate plans to "upgrade" to Lion because I really don't like it, having played with it at the Apple store. Also, it won't run my Quicken for Mac and I like Front Row and don't want to give that up. I've also heard people having lots of streaming video issues with Lion.). When I bought my iMac, could not decide whether to get the Track Pad or the Magic Mouse, so I bought both. Now that I have had my 27" iMac for about 2 months, here is my opinion of it so far:
The good: Basically, I love this computer. It is definitely fast enough for anything I need, and it boots much faster than my Previous Dell PC (Pentium 4 running XP). Even Windows 7 boots very fast! I have had no issues with the display or anything else so far. Luckily, my system did not have the hard drive that had been recalled.
The Bad: My only complaints are not with the computer itself, but with the peripherals. First, I like the "look" of the keyboard, but personally, I prefer a "real" keyboard as I just can't get used to these tiny little keys. I really think I'll eventually try to find an older Mac Keyboard that has "real" keys that have (for me) a better tactile feel. Maybe I'll eventually get used to it, but so far I have not. Second, I like the Track Pad, but the magic Mouse sucks. I can't hold it comfortably without constantly causing unintended mouse scrolling and other unintended actions anytime a finger accidentally brushes against the top. It's a good concept, but in practice it can be very frustrating to use (at least it is for me). I have turned off the Magic Mouse and placed it in a drawer. I'm now using the wired Mighty Mouse that came with my Macbook (which has its own issues when that tiny ball gets dirty and stops working well).
