Love the PB with OS2
OS2 now includes Adobe Reader (and also Docs to Go) so there are multiple choices for reading PDF's. Best of all, Moon Reader works extremely well - just like on an Android device and includes autoscrolling - the best way that I have found to read books.
There are many other Android apps that have been ported - just amble over to Crackberry forums. Also, the PB is well built and can play media, etc.
