Right now I'm using just 2 devices for all my needs. (Windows 10" tablet and cheap Windows phone). It works pretty well because I get the mobility of a tablet and pen support when out and about and when I'm deskbound I simply dock it to a 27" monitor, full sized keyboard and mouse. I get portability and the desktop experience all with just one device. But I do miss my Apple devices. Mainly the build quality and rich app selections for iOS. I simply got tired of the limitations of iOS on the iPad. It was great for simple things and I think I could actually eliminate my OSX needs if only iOS worked more like a Windows tablet. Yes, it can handle a keyboard and external monitor support is mainly for watching video because it won't scale anything else correctly. And of course there's no other input support available to iOS other than touch. Plus, no stylus support (I don't count those huge, rubber-tipped mushy faux things). I would love to see the rumored iPad Pro incorporate OSX or a ramped up version of iOS so it could do all these things.
