I got the Toshiba e310 its a great unit i got it for a very low price like 70% off kind of a thing so i bought it any way. The unit does drain the batteries in a day i may use about 60% of the battery max. only. i have not had any problems with it what so ever, only down part is that it only has 32mb ram and 32mb rom, but with the 256mb SD card the movies and mp3s play very nicely on it especially after the rom upgrade from toshiba. also it came with pocket pc 2002, pocket word, excel, ie, msn messanger and some other apps.
