I was so excited to see my New X51V yesterday when UPS guy handed me over but it all disappeared soon enough when I had to press reset button after 10 mins. and since then I really do not know how many times I have done that (unit is freezing up).Another shock came when my laptop won't sync x51v

. I tried to call Dell and they asked me tp update to Active Sync 4.1. No luck even after that (changed all the usb ports,turned off all firewall and antivirus s/w). Then he asked me to install it on my desktop and it worked fine. But I really wanna sync it with my laptop.(all my USB ports are working fine with other hardwares).
Please people let me know is it a defective unit or common for X51V.TIA!
