playbook is fine
The playbook seems a decent device. RIM's problem is, their key market is enterprise email, and they charged about $30/mth per user for the privilege. Now that anyone can get email on their smartphone, WITHOUT having to pay this $30 charge, RIM is losing money. They still do well since Blackberry Enterprise Server, despite being rather crap sometimes, is a useful bit of software for administrating phones. However, they are sliding down a slippery slope and I don't see anything for them to grab onto unless they come up with something totally new.
