^ It's true that Maremo is "normal" Linux kernel, which is converted for ARM processors, but I still wouldn't say that Maemo is computer OS and Symbian is for PDA's.
Basically only difference between those two is that Maemo is much newer OS and it doesn't have weight of the past slowing it down. Both can do same things, but in Symbian all changes takes a lot more time because of those 40 milloin lines of code, which aren't always done best possible way. Maemo uses veru flexible Linux kernel, which can be used almost everywhere with minor changes, just like Linux based Google Android.
