Hey! So I thought about it and I think I am gonna go with the current 13" MBP. I think the Core 2 Duo is fast enough for my needs ( just casual use like iTunes,Chrome,Garageband and maybe some Aperture).
And I think when I get a nice SSD after I got the MBP it will be fast enough.
Or am I wrong that you won't notice much difference from the new sandy bridge to the Core 2 duo??
With these needs you'll notice a lot more from an SSD than from a CPU upgrade. That's why the "underpowered" MacBook Airs are running circles around many of the MBPs. But SSDs aren't all that cheap at the moment. Since the prices of the MBP won't change much, just the specs, you can do two things:
1. Wait for the update; buy the old (current) model for a cheaper price; upgrade with SSD.
2. Buy a new MBP (which might or might not have an SDD by default I'd surprise me though).
In the end you'll spend more or less the same. Personally I'd go for the second option. You can always buy an SSD later when you don't think your system is fast enough and prices drop for larger SSDs. Also, the resell value of MBPs with C2D CPUs will be way lower in a while.
