Hi guys, I had an iPad 4 for a week or so and I wasn't impressed. Unlike my Macbook, which I enjoyed from start, it seemed needlessly restrictive and not well thought out. Now I'm considering getting the Air 2, but I want to ask about some of the functionality first. Can the Air 2... - use WhatsApp Web? - do the picture in picture thing with Netflix? - use a BT keyboard to SEND messages? As in press enter, send the message you just typed. That seems like the most obvious keyboard shortcut EVER, yet for some reason it didn't make it into iOS thus far. I'm hoping that changed when Apple paid a bit more attention to keyboards due to the iPad Pro. - actually download / save files like MP3s or PDFs from the internet? I remember being able to open them in Safari and listening to them straight away, but not being able to save them permanently to the machine. And if you could recommend a small external bluetooth keyboard that isn't much longer than the iPad, please go ahead. Oh, and how much space does iOS take up? Around 6 GB? Thinking on whether to get the 16 GB or 64 GB version... Thanks!
