I think I have been demoted to a hard drive
At any rate, I will add one thing on to what Kakaze has said. Right now there are enough rumors swirling and a few things to back them up, that I think that if yu can wait until the next product launch by Apple it might not be a bad idea. The main thing that has me saying this is that apple has informed its stores to go ahead and order at least 4 weeks worth of stock according to sites like ArsTechnica, and there is at least one product transition incoming by the end of the year we are pretty certain is going to happen, we just aren't certain on what it is. Most of their lineup short of the iPhone are canidates for a refresh though, so it might be worth waiting til early to late September if you can and choose to.
Not to say that the current lineup is bad, I quite enjoy my older MBP, and my Powerbook before that.
PS ^ For the record it is Seablade and not Seagate
Seagate is a hard drive. Seablade is me(And one really crappy X-Box game that stole my handle)
