Yup, my bad.

So, powerwise, how well would a linux-based pda work compared to a palm
pda at this point in time? Naturally, there are various fudging factors
but normalizing for a specific feature set and utility (take your pick,
I'm not fussy), how far does the kernel still have to go? Presumably its
the same for mobile phones?

How do other free operating systems fare in this regard?
