We have the V-Smile game system for the TV, and the Leapster (My oldest son got the L-max a few years ago--- but we never used it on the TV, and we just got my youngest the regular leapster-- which has been great, he doesn't even realize there's an L-Max, and there's only a few games that need the LMax). I like having the two different systems, because there's a bigger variety of games, if you have one of each. We've had the v-smile for years (we got it for my oldest son 3 or 4 years ago), and by now there's only a few games we don't have--- so it's nice having a larger variety. We did the same thing with my oldest's game systems. We have Playstation for the TV, and Nintendo ds lite for his pocket games--- that way he also has nintendo games (mario brothers) that he can choose, as well as Playstation.
Also--- I wouldn't invest too much into V-tech. Vsmile is great, and I recommend it, but when I had a problem, V-Tech wasn't very helpful-- I ended up buying another system since we had the games. We've had problems with both Leapster and our Leap Pad, and Leap Pad fixed everything for both of them free of charge, no questions asked-- they didn't even ask for a receipt.
