Rumors continue that Best Buy and HP still have stocks of TouchPads that will be put on sale in the next few days.
I've had a TouchPad, purchased from Best Buy, for 5 days, and I enjoy using it. After loading the OS upgrade and turning logging off, the TouchPad feels roughly as fast as my original iPad. I like the multitasking and the card metaphor used in the interface. And it's nice to use an onscreen keyboard that has a Tab key (convenient for navigating between fields during data entry, instead of touching the screen).
3rd party applications are very limited in number. The QuickOffice app is currently read-only for files created in a Microsoft Office application, but the company says a version that can create or make changes to files will be available in a few days.
I took advantage of HP's free offer of the Audubon bird guide for North America, which normally costs $15. It took three tries to successfully download from the HP App Store server and install the 2 GB of program data. It's lots of fun to see photos and listen to songs of the birds.
So far everything seems to work OK, with one exception. The web browser included with the TouchPad (upgraded to 3.0.2) has had problems displaying some Google GMail messages. Sometimes long messages can't be scrolled to read to the end. And messages that have lots of graphics don't always display properly. I don't yet have a solution that works consistently.
