Hello all, A couple of questions... I am in desparate need of a new computer to finish a project at the end of the month, as my venerable Pismo has packed up (screen gave up). I was hoping that new Tiger-compliant iBooks would be out in time, as they hit the price-point I was looking at, but sadly this does not seem to be the case. I have considered the 12" PBs, but I am most likely going to buy an iMac instead. It is a carefully-considered compromise. Since I am no longer a student, I no longer need the continued portability of a laptop, but I will lug the iMac around to work occasionally (free wireless). My old art-school bag has the dimensions to fit an iMac of either size comfortably, and currently weighs 29lbs (I put in on a scale) with all it's art supplies, so the weight issue is covered. On to the point: I am somewhat torn as whether to buy a new (rev b) iMac or an older iMac, refurbished or closeout. On Apple's website, a 20" rev a iMac can be had for $1399 (1.8ghz, SD), or a 17" for $999 (1.8", SD) - both which seem like great deals. I do not care so much about the improved gpu in the new iMacs, as I do about the wireless and bluetooth options. Did the old iMacs have any of this standard? (esp. the 20") How difficult (and elegant) is it to add these features after purchase? Would this negate any price savings? I have had trouble finding out any info regarding these questions, so I ask you fine folks for advice. Thanks in advance. Any other comments would also be appreciated.
