Well, just to be the 'Devil's Advocate' here since all posts have been 'positive' concerning the desire for a screen protector whether one is really needed or not? The 'gorilla glass' on current iPads is quite durable - for myself w/ two iPads in the family, we've had covers but have not used extra screen protectors, whether plastic or glass - my iPad 2 is nearly 4 years old and is doing fine.
This has been a frequent topic of discussion, including this forum - here is a
THREAD from a year ago (and others exist); plus, simply googling this topic will bring up plenty of hits w/ both positive & negative comments as to the need for these protectors. Now, if I did not have 'covers' on my iPads then would probably consider one of these glass protectors, but just don't see the need otherwise.
This will continue to be a debated issue and there will be advocates or objectors to both points of view - so, simply wanted to raise the issue - Dave
