@t0flus : Great, thanks. I was mssing the side nav button thing !!!
So far, I'm very hapy with this device even if coming from HP 4150 I find it a bit heavy but I don't carry a phone anymore so, all in one, it is okay.
I guess the ultimate thing would be an SDA with Wifi:)
Other question : anyone of you leaving bluetooth always on ? Whith what impact on power consumption? I could not try yet because I did have the opportunity to try while staying close from power source during the day to cope with possible low on the batteries side...
