I was all excited to go out and buy a new 21.5" iMac this upcoming week when I remembered to check to see if any updates to the iMac would be made soon. In doing so, I came across a rumor that, reportedly, Apple is going to be releasing a 22'' touchscreen iMac in the second half of this year. What should I/would you do? Wait a few months to see if this rumor does indeed pan out, or just go ahead and pick up the current 21.5" iMac?
