I personally like the M4400, although I do currently have the LenovoT500 and I think it is a pretty powerful computer. I also use Solidworks as well as Pro|Engineer and I find that it works really well with both software. I actually prefer CAD on my laptop over my desktop........maybe that's because I'm always at Starbucks working at CAD at 6am!

Have you thought about just looking for a laptop with a really good processor and then upgrading the RAM and HDD? By the way, I believe Vista x86 only reads 3GB of RAM, so you will need x64 architecture unless you are going with XP
