This seems like a pretty good move for IBM (I doubt there's much room for expansion in their already small PC division (~$1B for them is pretty minor).
Personally, though, I'm rather disappointed by this, since t I actually bought those dang things from time to time when I needed to go Wintel--they seemed to be of above-average quality.
The old HP Vectras were workhorses, but the more recent few I bought were so bad I've given up on HP entirely, and it only took one set of Dells to know that I'm never buying from them again, but the last four IBM boxes I bought have all been nice and solid, and it was nice to have a reliable go-to company.
It'll take a while before I'm willing to trust this new company, so who the heck am I supposed to go with now?
