Microsoft Arc Keyboard/Mouse

Hi,

Just wondering if anyone has any experience of these two?

http://www.microsoft.com/hardware/mo...s.aspx?pid=112 and http://www.microsoft.com/hardware/mo...s.aspx?pid=120

I know the arrow keys are less than perfect, but I hardly use them anyway. I'll have to buy batteries every so often, but that doesn't bother me really, I don't want wires any more.

Just wondering if there are any alternative wireless combos that are better for around the same price? :)

the mouse looks nice,
keyboard is a let down with the directional keys though
