Any views on iPad/iPhone controllers for a Squeezbox? iPeng and Squeezepad seem to be the top contenders.

I discovered that I could use the browsers on my iPad to do this, but probably not good enough. To try do 192.158.0.xx:9000 in the address bar of your browser. The IP address given here as an example is the local IP of the machine with the Squeezebox server you want to use. Adjust to taste.
