Personally I didn't think there was anything wrong with the old ones however I can see the point of them of reducing the complexity of the UI which is good but needs to be done right.

For anyone not on Testlive here are how the new icons look:
Pointer:

Like it.
Trade person icon:
http://oi52.tinypic.com/jfauk6.jpg
Worst.
Hoover over item icon:

Not bad. Would prefer just the Cog Wheel.
Info Icon:
http://oi55.tinypic.com/2rd8eo6.jpg
Not bad but still.
Edit:
Maybe I overreacted at first, the new mouse cursors arn't that bad if you turn the settings down in f10. I still prefer the old ones I can live with the new ones though.
