Well it looks like the Tungsten X will be released in mid October - and we are looking at filling our set of Palms with 8 of these instead of a remaining 8 LifeDrives - mainly from the stability factor. Hopefully Palm release a patch for the LD soon that fixes its many stability issues! The Tungsten X will be a more affordable solution for students, without an internal HD, but still with BT & WiFi builtin. Coupled with a large SD memory card it should offer similar feature set to that of the LD for a lower price. We shall see!
