I said it earlier and I will say it again. I love Boxwave. If you don't want the hassle of the water install of a screen protector, and you want something that is easy on off and does the job well get Boxwave. They have for the EVO both Cleartouch anti glare and Cleartouch crystal. They are available right now for ordering. No, I don't work for Boxwave, but have used their products for a long time and they just work and you don't know they are the device.
Here is the link for my personal favorite, Cleartouch crystal. You don't even know it is on the device.
EVO 4G Screen Protector / HTC EVO 4G Screen Protector / EVO 4G Invisible Screen Cover / HTC EVO 4G Screen Cover / EVO 4G Screen Film - ClearTouch Crystal
not sure whats the actual screen looks like but according to the picture it looks like it will cover the 4 buttons on the bottom. will that have any effect on the buttons? just wondering.
