Hey all, it's been a while since I've posted here, but as always, you have been a steadfast and paramount resource for my technological life

I will be buying a laptop in the near future, I've read tons of review here and there, some comparisons, but a second opinion never hurts. I'll be using it for mostly for business and schoolwork when I'm mobile (i.e. programming, word processing, etc.), but it's not going to replace my desktop. Key concern is finding a balance between functionality and usage time slash battery life slash whatever you want to call it. Plus it would be nice to dual-boot Vista Ultimate and Linux

I'm leaning a bit more towards the functionality side...
So, without further ado, the specs:
Lenovo Thinkpad T61
15.4" widescreen (1680x1050 max res)
Intel Core 2 Duo T9300 (2.5 GHz, 800MHz 6MBL2)
SUSE Linux Enterprise 10
2GB PC-5300 DDR2 (2x1)
160GB HD 7200RPM
Apple Macbook
13" widescreen
Intel Core 2 Duo 2.4 GHz
2GB PC-5300 DDR2 (2x1)
160GB HD 5400RPM
I guess that's everything pertinent. I added integrated Bluetooth to the Thinkpad, upped the processor from the start and selected more memory and a bigger, faster hard drive to bring it up to spec with the Mac, and the specs on the Macbook are standard. Price is comparable, within a couple hundred dollars.
So... Penny for your thoughts?
