I primarily use SqueezeplayOS on my Joggler these days, and its main use is a replacement for my aging alarm clock (talk about using a sledgehammer to crack a nut!

I have noticed that under other OS' it's a little "jittery", but it's usually usable (though I switched from other OS' as few of them are very finger-friendly - even JoliOS).
Is this normal for Linux? I haven't tried the default OS/PnP in a while, and won't do until the issues with the new firmware are resolved. Every time I tried to calibrate the screen in other versions of Linux it made the touchscreen even more inaccurate, and left me with a dead-zone around the edge of the screen.
