Acer N30

Been looking into getting the Acer N30 for £160. This comes with an older version of PPC that doesn't allow you to run apps in landscape mode, e.g movies. Is there any way I could upgrade to a newer version of PPC or would I have to flash it? Also does anyone have any recommendations of other PDA's around this price range? Would really love built in wifi but would also need to buy a 512-1gb SD card for it :(

Have you tried a PPC-based forum? Im sure theres some good ones around that would easily answer all your questions :)
