Just like to point out that it would be awesome to have some sort of osmarender on the device itself.

No matter if I'm smiling to the networking gods or begging on my knees with tears in my eyes, internet is always a slow pony in my area, and Marble still throws away tiles before new ones are downloaded. Not always, but only at the worst possible time.

It would be sweet to 'just have it' like navit or commercial solutions.
