Zero click exploits are a thing, but they are very expensive and have limited shelf life (once they have been used a few times, they tend to get found out and patched). Most actors won’t use one, unless it is a very, very high value target. It seems that the EU parliament member was not high value enough, and got lucky.
The Palm Pre had the best mobile typing experience I have ever had. I tested a lot of different stuff (Blackberries, various weird looking Nokias), but something about the Palm Pre was just... better. It had the perfect amount of resistance, the keys were well defined and had a nice rubber touch.
