Would I be crazy not to get an a 20" 2.4GHz iMac for £850 inc delivery? Is there a decent performance boost over the 2 GHZ model to justify the price hike. I was planning on getting a mac pro, but this price is looking very attractive and with Leopard now out I'm starting to chaff at the bit. Frankly I'm sick of waiting for Apple to update technology that is over a year old including it's price. I'm expecting to upgrade it to at least 2GB. Here's my needs: Needs: CS3 Design suite, Windows running in Parallels, Boot Camp (possibly to run to run Battlefield 2). I have no mental video editing requirements but I expect I will do a bit of home video editing. This offer expires this weekend, so any feedback would be appreciated.
