I've got many programs on my Zire 31 which I bought on Boxing Day for only $149.99. I was quite excited. I also have a 512MB memory card as well for music purposes mainly. I've got songs of course, a better graphic-type calculator, Text Twist, ZLauncher and several other launchers. I also had a home-made movie on there at one point playing on MMPlayer. Yes, it actually works on Zire 31's. So does playing music so loud it distorts it almost entirely.
I had zlauncher on my Clie and I found it to be quite useful. Now it's mainly streamed line for business. I have work specific converters, calculators & formulae. I still have a couple of pics and some mp3s. I had purchased some games for which have the pass codes but I only played them for a short while and then deleted them. Never seemed to have the time for games because of my schedule.
