However, I finally give a try, and got Pharos Traveler 137E (no software card). Strangely, mine doesn't have problem some other users stated, I can assume it's different hardware.Touchscreen is reliable, no "single tap, multiple characters" issue.Battery is still kinda short, but I expect that happens, running over 3G is certainly battery killer, I have ordered 2 more batteries along with software card (137E has a coupon, which gives $50 off).Charging this Pharos Traveler 137 from USB hub works with a trick, that you have to cover 2 center conductors on the USB plug to make it NOT data capable, failure to do it will activate ActiveSync and halt charging; same way applies to iGo AA battery charger, NiMH batteries will work, but Lithium AA batteries are recommended as it draws a lot of power.The new hardware has better radio, no "losing reception" problem like other stated; however, the antenna is located on the bottom (back of trackball), and I hate this design,
