Hey, So I ordered a new mac pro and will be doing most of my work on a 42 in HDTV. However, when I simply want to browse the internet and other regular tasks (and prevent my eyes from melting ), I would like a 20" ACD to the side. If Apple updates the ACD, do you guys think the 20" will be phased out with a new 24" model becoming smallest? Or do you think it will remain, with a price reduction? I'm torn between buying a cheap used ACD 20" on ebay, and waiting for Apple to update them and lower the price. I guess if nothing is announced Tues, I will just look to eBay for the display. Thanks for any input.
