I'm looking forward for touchscreen-enabled handhelds support. Many PDAs out there have 800x480 and there is also upcoming Open Pandora that runs Linux (I'm about to buy one once it is released).

So, are there any plans on porting to platforms other than Windows, Linux and Mac?

There is a small possibility. It has been discussed, but no official plans at this time.
