[TriLUG] Laptop and L.A.M.P.

[matt-nc]

I'm thinking about getting a laptop that would run current versions of 
Linux, Apache, MySQL and PHP so I could work on learning those things at a 
library.

What would be the minimum hardware requirements for that setup to work 
pretty good -- ie. processor and speed, RAM, hard disk?

Any thoughts or suggestions on the subject would be appreciated, including 
recommendations of good sources for a used machine.

Thanks,
Matt
