Hello, I haven't purchased an iPad yet but am seriously considering it, even though I'm a 'PC' person and unfamiliar with Apple products. My question: Does anyone use the anti-glare 'cling' sheets to knock down the glare on the iPad? If so do they cause a lose of 'sharpness' on screen? That's ONE of the reasons I've not bought one along with the inability to use memory sticks and a 'normal pen' device. I'm used to a Wacom tablet and their 'pens' have a point which the stylus for the iPad isn't really pointed. Anyway, my real concern right now is about the glare. Thank you in advance for any help.
