I walk to work/run every day (about 13km - with extra lunch time walks and general wandering on way home, maybe 20km a day or so) with a couple of vita's in the back pack and the 3DS LL
Decided to check out Near distance travelled ....
Vita #1 : 462km - hmmm too low
Vita #2 : 23048km - erm....
3DS : about 3,000,000 steps
Why do you travel with 2 Vitas?
