True, I should've mentioned the purpose. So I would like to watch movies, stream TV shows, read emails, surf the web, and occasionally type up notes. I had the keyboard and iPad combo years ago and it worked fine. I had the Surface 3 and I regret moving up from it to the Pro 4 because I hardly used the Pro 4 and sold it.
Now, I am looking for affordability but being a good product and experience. My iPad 4 is bulkier and isn't as likely to get support for the future since 2GB RAM or more will get the better features. So I am thinking iPad Mini 4 or Air 2 vs finding a Surface 3 alternative since it's been discontinued and what is left on the market is terribly overpriced.
