I have been wanting an iMac for the longest time now. I have saved up my money to the point where I'm ready to buy it. However Sony introduced a new 24 inch desktop with 3D capabilities. It has both HDMI input and output. You can connect your PS3. it will even upscale 2D to 3D. Pricing starts at 1425 http://www.techrockstar.com/2011/06/08/sony-intros-vaio-l-all-in-one-with-24-inch-3d-touchscreen/ http://www.engadget.com/2011/06/08/sonys-new-vaio-l-all-in-one-thinks-its-a-3d-tv/
All in all, it comes down to whether you like OS X or Windows 7. The extra bells and whistles of the Sony are nice but the bottom line is you'll be using the OS the most anyway. If you need a hdtv to hook up your ps3 too then I guess go with the sony, but you don't have an hdtv already?
Why would you want to wear glasses to use your computer? If you want a 3D TV just buy one but the gimmick will get old and you'll still crave the great OSX U.I.
Wow saving money to buy crap. With $2000 you can build a wicked machine with a monitor and an OS or your choice.
^You can't build All-in-ones. What does "upscale 2D to 3D" mean? The Sony's also got a touchscreen, "24-inch 3D multitouch." That's a huge plus for me. If you can get it bigger, do it.
I don't see the advantage of having an all-in-one. So what happen if your monitor breaks down and your warranty is up? One thing breaks down you have to send the whole thing back. Another thing large standing touchscreen is fun for the first couple of days but I don't see the advantage of having to paid extra for that. I mean if it's lying down than it would be a different story since it's much easier on your arm if you plan on using extensively.
