I thought I had a Bad K2 last night since I wasn't able to play my MP3 music from the experimental page, but could play them from the content page ie: audio file.
Fumed about it till bedtime, then with a clearer head this morning, went back to rethink the problem. Plugged in the K2 to my computer and looked at the drive files. Ah ha! I had transferred the mp3 files into the audio folder instead of the music folder!

So moved them into the correct folder and now I have beautiful background music while I read. Nice!
Successfully bookmarked my business web urls and processed an order for a customer completely from the K2. Exactly what I was needing from the internet function as I fly down to visit my Mom soon and no internet access there but do have Sprint cell coverage.

Thank you Amazon!!!!! That and having current news and access to the big world is going to be awesome. Now I can relax and enjoy my time with my Mom and still stay in touch.
Bummer though, can't pay through Paypal from my vendor's shopping cart, but can use my paypal debit card so that's cool. It all comes out of the same account.
