My advice is to get an ultrabook, or a thin, lightweight notebook. I have an ultraportable (not an ultrabook) as well as an iPad and a desktop and really, the only time I really use my iPad is when I'm in bed because a laptop is quite awkward, like, I have to sit up instead of lying down.
Just everything is quite frustrating with the tablet because it has so many limitations. Web browsing isn't just as fast as a laptop. Apps are most of the time a bit of a gimmick, storage is limited and control is limited. One of the most frustrating things with a tablet (Android is better in this regard than Apple) is that they don't have a file system, so unlike Windows, you can't "browse the drives".
In many ways, I reckon, it's the fact that I have a laptop which I always carry around and the fact that I'm so used to Windows (which I've been using for the past 16 years or so) which just makes me connect more easily with my laptop.
Essentially, the only things I end up doing on my tablet these days is using it when it's impractical to use my laptop, using it for quick things such as checking my timetable and using it to watch movies and read books.
