Hi, I've just acquired my first Android tablet. I am an iPhone owner and can't face the thought of the cost of replacing my 3G iPhone with a new model at some point in the future so I thought I would investigate Android through buying a cheap 7" Cloudnine Neuropad Simplicity. So far so good. For £70 it seems to do all the things that I expected and seems just as good as a more expensive tablet, though the screen could probably be better, but I am not a gamer so not too important and photos look OK. I am still finding my way round it and one query I have is that every now and then a red border flashes up on the screen when I have tapped something. It only happens occasionally but it is not clear what it is indicating. Is this a common Android thing or particular to the Neuropad?
