We have the Explorist 200 and love it. Friends and family have opted for the 210 and I find it much slower to respond than the 200. The 200 switches from screen to screen without a hiccup but for some reason the 210 seems to take a while and for me, I'd rather stick with the 200 because frankly, I don't have the patience hehe. For the first while, when only my parents had the 210 I thought something was wrong with it because it took so much longer to switch views. That said, the 200 doesn't have the computer hookup.
