I don't know but I can't wait to try it. I've been on HAN a few times with a PDA and that wasn't too bad. Just expect posting to be kind of combersome. The rumor is that there will be small keyboards that you can get for the PSP in the near future. So then using the PSP for surfing might be a decent option. As long as you expect it to be a little slower than a laptop.

The best part about it is you can stuff it in your cargo pocket if you have a small enough case when you're out and about instead of lugging around and setting up your laptop, at say a coffee shop or resturant that has wireless.
