Crafty,
Those systems John found look like they would be right up your alley. I'm a bit impartial to the Lenovo, but that's just because I've enjoyed the performance of mine and it has held up to the abuse it receives with all my business traveling.
To John,
You're dead on when you say 3-4GB, but I still think it's a waste unless you get that full GB. I always found it silly that all the inter-hardware communication runs on the same 32-bit bus. And here's a more technical read you might like on Window's memory limitations.
