The best keyboard I found to use as an iPad as a laptop replacement is the Logitech Combo Touch. There are different ones for iPad, Air, and Pro. The keyboard and trackpad both feel great to work with and you can pull the iPad off if you want to use it as a tablet. On the plus side, staying in a case protects it (and it has a sturdy kick stand), but the biggest downside is that it adds a lot of weight. You’d just have to feel it to decide. I also bought a generic magnetic folio, which I use about half the time.
