TomTom GO-Is 200Mhz processor enough?

Hi all,
Very new to the sat nav thing, but thinking about getting the TomTom GO. I noticed from the specs that the processor is only 200Mhz. Has anyone who uses this suffered any performance issues?
It doesn't sound very future proof either...

Since the unit is dedicated to Sat Nav then 200Mhz is plenty as it only runs 1 program, whereas a PDA with 200Mhz would have the OS etc to run at the same time which would degrade the performance.

Fair point. Thanks Charlie!

well in fact, the TTGO runs linux and under that OS, runs the software to do the rest. however, linux is far better suited for such hardware compared to other solutions (and crash more often as well. I still have to see my TTGO to crash the first time)

Yeah that is true, same idea as the Palm based PDA dont need as much CPU speed as pocket pc. You will find that it runs much faster than PDA based Tom Tom
