Query: Ultra portable? Try ultra unreliable.

The VAIO arrived, looked nice and ran nice for 10 days. Then, the screen went dark. It didn't totally go black -- you could still see the outline of the objects you had on screen -- but too dark for you to be able to see anything. Turns out the inverter board blew out, which is what gives power to the backlight to make your screen bright.Now, I never dropped or mishandled the computer. And for pete's sake, it was only 10 days siince I'd bought it. Ridiculous. Someone who's worked in tech support told me VAIOs are known to have a lot of hardware malfunction and tend to be "delicate." I'd return it if I could, but I bought it here on Amazon. Luckily, there was the 1 year warranty.My recommendation is, if you want to try out a VAIO, buy it from a SonyStyle store, so at least you can return it if you decide you don't like it. But the best way to go is to get a different brand notebook altogether and not dealing with the hassle of an unreliable machine.
