Just thought I'd report that PON runs fine on my netbook. It has a small CPU, which I was worried might not be up to the task, but I get through turns OK. It's not what I would call quick, but not unplayable by any means.
I've got a Samsung NC20 which has a 12-inch screen. I bought this type of netbook to have a display area suited to AGEOD games. It runs all their other games perfectly well, and I was pleasantly surprised to see PON fire up. I look forward to playing PON on my next long flight to the US from AUS.
