@monami,
Can you give us a bit more of a review of the performance and compatibility of your PSP running UAE? What games work, how well do the the PSP controls emulate an Amiga joystick and/or mouse. Can any games that require type written passwords be played and how are you able to enter such passwords?
PSP has wifi, right? It also has a web browser, correct? My wife's oldest child from another marriage has one, but I never looked at it closely. If the PSP has a few utilities, like a calculator, date book, address book, email capability, web browsing, etc. such that it could replace my very old Palm Zire that I use seldom, I would consider getting one. The Zire does not have wifi, internet, or email, but I use the weak camera and the date book/alarm features some times.
