It’s looking like there will be an official keyboard for the PSP, you may have read my earlier posting on mobile device text entry in particular I was quite scathing about text entry on the PSP.
Text entry on the PSP is to be brutally honest only something you want to do only on the rare occasion. I find the mobile phone type entry somewhat comple, more so if you need to enter numbers at all.
A keyboard will certainly make it easier for users to enter text and urls, so is to be welcomed.
Obviously this will be too late for the current MoLeNET projects, but if you have bought a bunch of PSPs then you may want to consider getting these when they become available.
