My experience with the iPad put me off Apple products entirely. Well I have also played around with a friend's MacBook and found the whole experience very unusual. This was back when OSX looked like a candy store, with these glossy, candy-like icons and screen elements. I found Apple to be very big on cute stuff -- cute design, cute effects.
I too, found the same issues with my iPad.
Instead of going down the Surface route, though, I bought the 11-inch Macbook Air.
What I really need is an austerely-designed, flexible work machine. All that eye-candy is not necessary. I have written a thesis before in Latex, so I can deal with a raw interface. When someone hands me a USB stick with documents on it, I need to be able to read and edit them.
What really binds me to MS is Office. In particular, Excel. I've downloaded various spreadsheet apps and used Google's spreadsheet and they all suck so bad. Only Excel is Excel.
