I have a quandary, I've convinced my boss to buy me a new iMac and am eagerly anticipating getting it if after Tuesday's (much anticipated) refresh date for the iMacs. Should I try to get the 27" or is that just too big to work in front of all day? Who uses the big boy for work out there? Do you like it? Does it strain your eyes? Let me know. A 27" iMac might eliminate the need for multiple screens. If i go with a 21.5" then I may need an additional screen. P.S. Im doing web development and database work mostly. Thanks all!
