i use the mipad 2 with an ipad mini keyboard, the belkin fastfit, and the magnetic catch don’t work, the mipad 2 isn’t magnetic, and putting the tablet in front of the keyboard don’t put it to sleep.
But windows recognize the keyboard and you can type normally on it (there’s just some key missing, like escape, ctrl or delete) and the tablet fit the space in the keyboard given that the dimension is the same (20cm) as ipad mini
i hope i’ve answered your question 🙂
