I use my tablet (iPad 4 with LTE for $10/mo) for a fair number of specific tasks, but I prefer a laptop/desktop generally. It rocks on planes, as a car nav system in a rental car, for reviewing applications (...), for instapaper, for bathroom computing, for reading PDFs (although sometimes I use a Kindle DX), etc. Maybe I'm old, but using an iPhone 5S for reading long articles is kind of painful.
