Review on Macally Mac Keyboard Full Size Extended by Paul Wall

The keyboard was concave on the bottom and curved down to hit the desktop when typing. After a few months (not used for typing - just email and online stuff) it flattened out a bit. But it still bangs on the table as I type. In the meantime, I've noticed that many of the keys in their corners can be fully depressed and don't register a keystroke. Well, I'm not an experienced typist and I don't hit every key exactly. It's annoying to go back and correct missed touches. I've had previous Macally keyboards that didn't have these issues. By the way, what happened to the USB ports that used to come with Macally keyboards?
