Hey null, I thought you might find this interesting:

One of the first browsers to show up...still not perfect, but it's getting there.
Also: You bring up an interesting point with photoshop. The handhelds might not be able to run them, but someone might come up with a PSPgimp program or or a NDSgimp or something. It would be like a stripped down version, but still pretty cool.
Probably would be better than MSpaint at least.
