I currently have a 2009 MBP13 and it's not powerful enough for my needs anymore. Mostly working with really large excel sheets, audio editing, and boot camp gaming. Actually it never was enough to begin with but I didn't have the budget to get anything more than the cheapest uncustomized MBP until now. I'm hesitating between an iMac or selling my 13 and buying a MBP 15 instead (I feel the 17 isn't mobile enough). I'd rather keep my laptop because it's still a great machine and if I have another powerful computer, its current shortcomings won't be an issue anymore, but I'm getting a bit impatient. Any idea when the new iMac are coming out? On the other hand, with a MBP 15 I'll have all my data on one computer and won't have to worry about syncing/transferring stuff. Besides having a large screen isn't very important to me. So the MBP 15 certainly has its advantages too. Thanks for your advice.
