I suspect that I'll have to buy one for a pda with a bigger screen and "customise" it...
In my experience the Fellowes branded ones dont lift when you trim them.Be carefull, bought a proporta screen saver that needed a bit of trimming to fit my P3300 and decided I would cut the thing. Turns out that when you cut the plastic it tends to lift the sides and you don't get a flush fit on the edges. It's no that bad but my OCD get's the better of me sometimes.

The screen protector I got in the box with my P3300 had a soft feel to it
