New computer

My present computer, new in 2005, is physically falling apart. Reluctantly i got a new one, knowing it would be a nitemare transferring everything over and making it actually work in a new operating system (Windows7). Sure enough, my Verizon wireless modem (which i depend on for internet access everywhere beyond coffee shops and WFD) doesnt work. I spend hours on it, including long time on phone with a Verizon tech, who in desperation finally tries to blame it on Dell. Regardless, i'm the one screwed.
