I bought a 27" iMac and immediately fell in love with it but found the resolution to be too high so I ended up returning it. I found that for movies or games, I had to sit far back in order to view the entire screen. But for browsing the web or using MS Word, I had to sit close. So it kinda became an epic battle of either leaning back in my chair, or sitting up close. The 21.5" iMac had a good resolution but the screen is a little small. I ended up getting a MacBook Air and got a Dell U2412M with an IPS display for about $285 during Black Friday. After hooking it up for the first time today, the display is pretty brilliant (of course not as good as the iMac) but for such a cheap price, it is pretty amazing. Not only that but it also has a resolution of 1920 x 1200 so I get that 16:10 aspect ratio for extra vertical space and the font is much larger for viewing the web. I also added the Apple Wireless Keyboard and the Magic Trackpad to complete the experience. Anyone else compromise? Since the iMac only comes in two sizes, I find that connecting a portable Mac to a display gives you that iMac experience but gives you the freedom of whatever resolution or aspect ratio you want. The only negative is that the GPU won't be as powerful but it is a good compromise in having choice over the display, and unhooking the laptop take it on the go.
