Anybody using PDA software?

I was just curious, anybody using a PDA to trade? If so, what software? And the followup would be, how much horsepower does the PDA software have; can I put customized indicators on it?

I thought MetaTrader has a PDA version...

it does but I never tried it because my PDA is weak. From previous thread, it was not recommended. But I think the software is more advanced now with great charting features. I will have to try it out soon.
