Stupid Vista. Just got a new Gateway since my seven-year-old Dell is just too slow and full, but half my programs won't work on Vista (though, helpfully, several software companies offered to sell me upgrades ranging from $125 to $300. How nice.).
The worst is that BestBuy seems to have mangled the data transfer, both not transferring everything to the new computer, but preventing me from accessing the old computer (no boot drive). Nice, again!
