The PB shows why we need RIM:
1. Only tablet maker to push for built-in tethering. Apple pioneered paying another monthly fee for a tablet, and the Android makers are even worse- the first two flagship tablets were 3G only at first! Glad some big company is willing for fight for the right to tether.
2. From my experience it seems to have a composite based OS, putting it in Apple's category.
3. Android compatibility- might be useful if Oracle kills Android.
4. Only major tablet with 7 inch screen! Its screen is probably the best on the market.
5. Has a lot of fresh ideas for the tablet market and pushes a lot of useful benefits like true multi-tasking.
