I'm going to leave both of mine as is since this version is supposed to have a Flash fix and I use Flash sites a lot. That is until I discover some sort of issue then I may have to re-consider. Hopefully 2.1 will be out soon and it won't matter anyway lol.
Don't forget that you can 'test' 2.1.0.x with the developer/beta.. I currently have 22.214.171.1240 which was released earlier in the week. You can sign up at BlackBerry's site and enter your pin, wait acouple of minutes, then check for an update on the playbook.
