Are MacBook Pros 64-bit yet? The tech specs at Apple don't specifically say, and there are reports from a year ago saying "64-bit MBP in coming months!" but nothing recent.

it is, once leopard comes out everything will be
Well you're partially correct, the MacBook Pro has been 64bit since it came with Core 2 Duos. But once Leopard comes out everything will still not be 64 bit, only Core 2 Duos, G5s, and the Xeons in the Mac Pro will be 64 bit.

Gone but not forgotten.

Okay, we won't tell you that but it's not likely that most software converted to be 64-bit compatible will run as well or faster. It really depends on whether the application's needs are large enough to overcome the extra overhead of writing for 64-bits. Large database systems and 3D software are really the only things at this point that qualify.
