@smoku: yea, i've heard of stantum for a few months already. Unfortunately I haven't heard of any real products with stantum screens. So I've no idea what their real performance is like. For the time being, I haven't found any resistive screens that provide good performance for onscreen-keyboard touch typing..

@devu: i hate invisible shield type protector too... though they're tough like ******. they're especially nasty if you use them with a sharp-ish stylus. they stick and fold around the tip of the stylus...
I use matte-protectors on my devices (iphone, ipad... i don't use the n900 much, so it's nude).
