I have a vx6800 and the pn-820. I love my 820. I use it when I am bored with my 6800. There are obvious limitations when coming from a pocketpc to a smartphone but being that it is a flip phone is a big advantage. The pn-820 is not an upgrade but not a downgrade either. Really they work the same. You will probably miss the full keyboard from the Q, but you will get used to it very fast. Plus all the software you have from the Q works on the 820. Yes anything you can do on the Q, you can do on the pn-820. At $10 bucks you can't go wrong....Enjoy!
