During the first week the mouse pad and the battery had problems; the former was unresponsive at random intervals and the latter didn't charge well, going all night plugged in and having %76 in the morning. oddly enough these problems went away after the first week. But even after that it wasn't a great system: software aside i didn't feel like it had the power under the hood that a 1.5 GHz processor and 4 GB of memory should have had. To top it off it had trouble connecting to the internet via wi-fi, a problem that didn't go away after the first week. In general i felt it wasn't worth the $XXX i paid for it on sale, and the thought of paying the full $XXX is simply horrifying.
