Just ditched my 2011 i5 2.7 Mac mini w/AMD 6630.
Been PC/Windows for years (and C64 > Amiga before that) and after buying an iPad 2 in July, I decided I'd had enough of the PC upgrade roundabout (for gaming) and bought the mini.
Fast forward to 3 weeks ago and I'd had enough of the mini, but only from the point of view I found it a little slow and restrictive from what I'd came from (W7, quad core AMD, 8gb, SSD + mechanical, AMD4870).... I missed the "grunt" so to speak, so put the mini up for sale and bought this:
2.7GHz Quad-Core Intel Core i5
8GB 1333MHz DDR3 SDRAM - 4x2GB (upgraded to 4x2GB with spare sticks from mate's new iMac - score!)
1TB Serial ATA Drive
AMD RadeonHD 6770M 512MB GDDR5
Wow! The screen is something else, and although I've not got an SSD installed, there's a visible speed difference between the 5400 and 7200 drives. Much happier with the iMac, although I have to say the mini is still brilliant.
Possible new job where I'll be away from home through the week _might_ dictate a laptop, so there may be an MBA or MBP on the horizon, depending on location.
I did have a brief affair with the mini when they first came out, but purely for research purposes for work.... now I've come back to the Mac, it feels "Amiga" again! I do have to admit though that W7 on the machine I had was perfect - the SSD was lightning fast and I'd not reinstalled Windows in over a year since I got the SSD, as it "just worked".
I'm here for the long haul now though....
