Ok, just so I know.
Tbh I don't do anything straining on a laptop, I got my iMac for that...the only reason the RMBP attracts me is the weight of it, I won't need a CD drive so I'm happy to sacrifice this.
If the older ones weighed the same the spec would be fine and I'd have it in a heartbeat!
Meh don't know who I'm kidding, it's a matter of time before I buy one
although I've spent too much on new hardware this year.
