Thank you, Ian. That would have been a deal-breaker for me if 37b5 ROMs didn't work. I really like the look of Pandora, and want to get one.
I'll probably need a little help setting things up a bit, I'm intermediate-level at best with ths sort of stuff, but I managed with a Dingoo, and installing Dingux on it, so I can't imagine this will be much harder to manage as long as there's some good tutorials/instructions available to follow.
Mostly, I want to put a lot of games on there, a few apps, and use it to check web-based email while on the fly.
Was going to go with a Kindle Fire...but I think I like this better...Kindle don't do MAME...not that I know of, anyway.
