Following my earlier posting where I wrote about a delay of HTC's much anticipated Shift UMPC, DigiTimes Taiwan today reports that HTC is delaying volume shipments of the Shift UMPC to January 2008, instead of the third quarter 2007 as originally planned (which was postponed to fourth quarter later anway).
Market sources indicated, that HTC has faced problems with both - hardware and software - which causes the delay. That's definitely the worst case if a brand new device (and keep in mind, so far HTC was manufacturing PDAs and smartphones only but not PCs) faces problems with soft- and hardware.

While we have no further information yet what's the problems are, I can see possible problems with the swivel-mounted display mechanism as well as with the cooperation of Windows Vista and the stripped-down Windows Mobile version which syncs anyway (while HTC isn't using Windows Vista SideShow which was designed for exactly the same task).
