So…going back to the OP’s question. I have a new iMac (base spec 21″) sat in the corner at the mo. Having used pretty much every mac since the late 90s (work in a design agency), I’d say it’s the nicest desktop machine I’ve come across. Am sure the 27″ will be better still.
The screen is really, really nice. Noticably better than the last gen – not just the glare (or lack of), just seems really vibrant. Speed-wise feels about the same. The older machines look amazingly boxy in comparison.
This one’s actually soon-to-be my mum’s, replacing an eMac which is still going strong after 8 years. In the same period my dad’s been through 4 PCs, had the pain of crap AV software, backup woes etc etc. Given I’m IT support to both of them, I know which platform I’d recommend.
I only wish they’d keep the numeric pad on the damn keyboard…ho hum.
