A bit pricey for a mouse replacement.
A decent wireless mouse will usually run about $40 or so, so with this being $69 it's not bad actually.
first off tablets are horrible Replacements for mice, if your playing games. But for general use And/Or special use (eg photoshop) then you want ones that are screens aswell, although they are £500 +
A regular tablet, yes, but this is like navigating with a touch-screen of sorts. It really is cool.
