I've been purusing the ME forum and general opinion is ME needs LOTS of resources to multitask. I have two machines running ME. They're practically identical- 128meg, 15gig HD, 400 MHz. One machine handles internet connection sharing (ICS) for the rest of the house. It does e-mail, web surfing and can handle word processing and Excel-not all at the same time though. The other machine is in the same class, but doesn't have to handle ICS. After a couple of bouts with spyware, trojans etc., I think it's safe to say ME really can't handle multi-tasking, like,, at all. Unless that old pc has 257 to 512 megs of memory and at least a 700mHz processor tucked under the hood, I'd say forget it. Leave your old machine alone-use it for checking, taxes, word processing and so forth. Save your money and put together a new machine that'll run XP. It'll blow your socks off.
