The cost is the factor. No need even to think about it when a used one, provided it works costs about $100 or less for similar 1999 models. Sure, someone may pay more like $150, but if it breaks, do you really want to fix it, is all too often the deciding factor to pitch or donate it. I have Thinkpad 365XD, it works but is only a backup at customers sites when thier system is blown. It helps to access the www to get the drivers, etc. and still is reasonable to lug around. Sure, a $700 laptop is better, but since it maybe stolen, dropped or flat out given me it last days, its worth to keep for now, but once the battery is no good, I'll donate it. Why pay $100 for a battery when in all likelyhood, I'll find a whole replacement for $75. Of course the local sources to me are decent, the choice is yours.
I am on the road alot in my job and have lugged around an old 1999 IBM Thinkpad that doesn't work half of the time and I can't get to hook up to hotel intenet connections The organizations tech guy, an outside contractor, wants to "rebuild" it. To my thinking we're still going to have a 6 year computer that is woefully outdated. My question is..how much is it reasonable to invest in something this old when dell has a new laptop on line for about $650. Anybody?
