@Digit_Dragon, it has been out for a long time now.
@apoorv.sharma, you got that right. *sigh*
@gx_saurav, if you want bigger buttons than on that thing, you've got a gorilla's hands. The entire body is the button. How can you expect it to be larger!
@Kiran_tech_mania, yes, it is pretty darn expensive. I would've gotten one for myself had it been cheaper.
@gx_saurav, it uses touch sensing to figure out which side of the mouse you have pressed to determine whether it is a right click or a left click. You still have to press it physically though and you get ample tactile feedback with a familiar 'click' sound. And you'll never want to go back to ordinary mouses once you've experienced horizontal scrolling on the thing. (Then again, I am not so sure. After all, you are a person who prefers Flip 3D to Exposé, complexity to convenience!)
@pra_2006, It is very highly not recommended if you are using Windows or Linux. Plus, it is expensive.
