All --

I have a Toshiba Portege 3505. I loved it at first, but then the
digitizer stopped working. There would be large areas on the screen that
just would not accept ink. It was still under warranty, so I got the
digitizer replaced and it worked great for about 3 months, but then the
problem came back (this time in different spots). Now, 6 months after
getting it replaced, the digitizer doesn't seem to work at all and the
Tablet pretty much doesn't accept any ink. Has anyone else ever had this
problem? It's still a fine laptop, but basically useless as a Tablet. I
am considering getting another one, thinking maybe my particular machine
is a lemon, but before I do that I want to hear if this is a common
problem with Toshibas (so maybe I should look at a different brand) or not.

Any insight folks could provide would be greatly appreciataed.
