The iPhone excels at anywhere/anytime. But for a session of any appreciable length or complexity, the screen is a limitation. Laptops are great for sessions of length and complexity, but the ergonomics require a traditional desk and the overhead required isn't justified for many tasks. A tablet would land between them. Essentially, every place you're still using a legal pad (for meeting/conference notes), dead tree reference (for reading/reference consumption in a comfy chair) or fixed-function device (portable video player) because phones and laptops just aren't the right tool for the job. If you don't find yourself doing any of that, maybe a tablet just doesn't make sense for you. But that's no different than conventional laptops not really working for me. (Clearly, there are plenty of people for whom they do work) As for the ergonomics of a tablet - it's not going to be much larger than a kindle. You'd be able to comfortably one-hand it, like a book, legal pad or kindle.
