Chippy of UMPC Portal got his hands on the new HTC Flyer, the one with dual touchscreen layers. He puts this Android tablet though its paces, and 1 of the apps he shows off is a reading app based on Kobo. The new app supports scribbled notes.
Now, this isn't all that new of a feature; some ereaders have been doing this for years. But when it comes to the Big 3 (Kindle, B&N, Kobo), it is new. None of them have apps that can do this yet. TBH, Kobo can't quite do this either. All these features are based on code written for the HTC Flyer.
The video is after the break; skip to about 5:10 to see the Kobo app.
