I think Windows 8 is great on the desktop and 8.1 just makes things even better. However I'm still not convinced that a Windows tablet is better than an iPad for what most people use it for.
Saying that MS are definitely on the right track with the fully functioning touch devices with full Windows, we just need the hardware to catch up a little and their shouldn't be a need for two separate devices in the future. However the technology just isn't there yet, I just hope MS doesn't abandon the idea and follow their recent trend of changing direction.
I like the way that MS think that the on screen keyboard is great with the type ahead feature. Have they even looked at the Google Keyboard with their swipe functionality or even SwiftKey? Miles ahead.
