I have the original transformer and use it for work stuff when I’m travelling (and don’t want to haul my macbook all over London). It’s fine for email and some basic office stuff (I user Polaris office which is about 95% compatible with Office 2010, does some odd things to PPTs)
The trackpad drives me nuts so I have a bluetooth mouse. It’s a bit odd sometimes touching the screen and having a kbd (and the screen makes it a bit top heavy) but it’s way better than a smartphone and a shed load lighter/smaller than my Mac
Best thing is in the Hotel I just watch movies etc and it’s brilliant for that.
Not dome much photo editing. It’ll talk happily to my camera (having USB is good) but not installed anything to do proper PS like stuff.
