I have a 64GB one and love it, its fast, true multi tasking, fantastic screen, brilliant speakers and in OS2 will have native email if thats your thing. The only negative is a lack of applications for the device, but as OS2 will support android apps that wont be a problem from next month.
The device supports, HTML5, Java and Flash by default, streams from BBC, ITV, Channel 4 and 5
As for a "Techology dead end" 90% of the reviews rave about the hardware and the QNX OS (which Porche will use in there higher end dash). They all say it is let down by the application offerings.
Personally, i dont like the 10" Ipad size or anything Apple as i find it far to restrictive, and Android isn't secure enough for my needs.
