Given the hoo-ha reported on this site regarding WM5 (installed natively and as an upgrade) the report that Fujitu-Siemens - manufacturer of the Loox PDA - has cancelled WM5 upgrades for the devices is not a great shock.

Still, its a pity that Dell Axim users had to be the guinea pigs.
Meanwhile, I got my invoice from Dell yesterday, reporting that my 'free' WM5 upgrade CD has been fulfilled and then a little later, Purolator (I'm in Canada) called to let me know its in. I'll get it today, but it won't be installed anytime soon. Rumour elsewhere is that there is a patch due out around November 18th. #1 in many, no doubt.
