4.You are Stuck with 366 mhz,sorry

6.&7. Ibought one of these IBM 600e units for my mom;400mhz 128 mb ram,10 gig hdd.........This is a really nice machine by the way(Even my puter guy got rid of his crappy dell after handling this and the other 4 IBM thinkpads I put across his desk and bought himself a T22 like my favorite)
We put XP Pro on moms;before I took it to her I put it on my DSL via my PCMCIA wireless card.It functions as fast or faster than my Wifes Dell you see in my sig.
I have bought 5 of these IBM thinkpads and have not been disappointed in any of them yet.Just upgrading to what I believe to be the most sound corporate laptop ever built;the T22(which by coincidence is the best selling laptop ever built,by a margin.
You do the math........regards
