I suppose. I just got a computer shammy at best buy. $9. It works great, I don't have to worry about scratching the screen and it comes in its one case so it won't get dirty. G
I suggest you get the LCD screen protector. I have a hand held game, Nintendo DS. I've seen what happens with NO protector, and how much the protector helps! I plan on getting one for mine. There is one here for $18: Sigma Automotive – Toyota Hybrid Prius 2004 - 2009 OEM & JDM auto accessories Scroll down to INTERIOR, it is in the left most column.
not really. There are no cleaning agents in the tissue to remove oils, etc from the screen. The tissue will leave behind fuzz. The tissue may scratch the screen.
