I'm not bothering to upgrade. My computer (Windows XP) is less than a year old, but I don't think it has enough memory (and I'm darned if I want to slow it down if it does).
My brother the geek has offered to install Ubuntu Linux in a dual-boot configuration. Really the only reason I need Windows is for dialing into the work VPN--we're a Windows shop, unfortunately. (Even the SERVERS! Eeeek! No wonder we get bitched out for using Gmail.) I even have to use IE to use the VPN client.

I think I can sync my Treo with Linux. Not sure. But there are rumors that Palm is doing something in the line of a Linux tablet device, so I would imagine there will be a way in future if there isn't now.
