I was under the impression that I will still be able to run homebrew with the 2.x firmware levels.... I am a serious newwwwb though.
As far as ISO's go, I am taking a new approach to the PSP (remember this is just my opinion, obviously not shared by many here due to the nature of "where" we are). With the Xbox I had so many games that I only ended up playing maybe a quarter of what I had. I got bored with games faster, had less motivation to finish games, so on and so forth. I noticed the games I bought I spent way more time playing, enjoyed them more and got more out of them. I plan to keep the minimalistic approach with the PSP. Although the idea of having every game at the touch of a button is cool, I know it won't be as satisfying. Homebrew roms excluded of course. I will use the memory card for video and photos, I really do like the idea of GPS (if implemented right) as long as they put out a decent dash mount with it. I like their browser, and would like to find/start a ring of PSP "Friendly" web sites. It is not like sony is implementing crap for features, they need a good keyboard (wireless or not) for the browser and it will be great for browsing while on the shitter or in bed. Now as far as hardware mods for this, I would definately be interested in trying this out. I liked having different dashes for the Xbox and would like to see what creative minds could come up for this device. Sorry for the drawn out thought....
