Query: Weak, awkward, obnoxious.

Bought it, used it for a day, was terminally underwhelmed. In no particular order, here are the salient points:1. It feels light, plasticky, and weak in your hand. Unforgivable at that price.2. The body has a big rakish slant to it and a tall hump in the middle; you love it or you hate it, and boy howdy did I hate it. Felt like I was struggling to keep my hand from sliding off, and it gave me really bad button-pressing leverage.3. Tilt wheel: worst feature ever. It's not even particularly useful, since it only scrolls a tick at a time. It also feels really loose and wobbly. That's a technical term, there. Wobbly.4. The middle button is far too stiff. I don't want to thumb-wrestle, pal, I just want to close that tab.5. The scroll wheel feels really sludgy.6. How, exactly, am I supposed to press those 4th and 5th buttons? Not that I have time to use 'em, since I'm so busy trying to beat down that middle button.In short, it is rubbish, and I'm returning it tomorrow.
