Query: Defective Palm M130

Though the M130 has nice features at a more affordable price, I am now very disappointed with my M130. It turned out to be defective when using an expansion card. The unit froze and resetting eventually no longer cleared up the problem. I sent my unit back to Palm and they are taking forever to repair my Palm Pilot. If you buy this machine, make sure to test out the expansion card slot as soon as possible so that if there is a problem you can return it to the store you bought it from. Corresponding with Palm has been frustrating.
