They do work well at what your allowed to do with them and if that matches what you want from the devices then fair enough.
i would keep my N900 over an iphone or android device any day
I have an N900 as well, and I love it.
What we need is a proper PUAE port though. Then again, I have a hard time getting a build to work on my desktop machine at this point.
I also haven't had much luck in using the e-UAE port or the UAE4ALL port. The first doesn't get much further than the configuration UI for anything I've tried, and the other I haven't been able to do much, but play a choppy sounding game.
