A few teething troubles :-
Video replay on Firefox not working properly (sound is there, but image is just a green screen) - now sorted
Battery charging - always says either 1 or 2 minutes to fully charged even when battery is down to 10% !
Scrolling on Touchpad still not working despite installing new drivers and stuff - deeply annoying
Now, do I delete the "old" version of Windows and free up 23.9GB of memory?
