Good choice, I just bought a T61 for my old dear as she just browses, stuck an SSD and 4gb of ram in it, with windows 7, owes me about £100 and its spot on for the cash!
My sister just recently came home with some Packard bell thing, spec was what I would have considered about borderline for usable tbh these days dual core intel, 3gb ram, the usual loads of space but s**t slow HDD, and it was terrible totally unusable! no wonder people who don't know much about computers get frustrated when they buy these things!, ive never saw so much bloatware on a computer in my life there was literally about 100 extra programs installed, I left the orginal install on it but just stripped it all out and it runs fine now!
