While I really like the screen of the iPad I am finding that it is not that comfortable to use even for surfing as you always have to hold it and touch it. I find it easier and comfier to surf with my MBP
Well, I've just upgraded from my iPad 3, and the first impressions of the pro are that its going to be a
lot nicer to hold for long periods.
Also, its very much a matter of taste: I don't like using a laptop literally in my lap, especially in a comfy chair: it feels precarious
and starts getting hot and itchy (somewhere in all that 'elf & safety bumf you'll actually find a warning about heat rash).
Tablets have their role, but are a bit overhyped - the industry talked them up because of stagnating and falling PC sales - now I suspect we've passed 'peak tablet'. My main use for my iPad is browsing the web & checking email from the armchair - plus testing my own websites on iPad. If it wasn't for the latter I'd probably make do with a cheap & cheerful android tab or just use my large-screen phone. I only upgraded to the pro because I've got professional reasons for wanting to play with Pencil support in webapps - plus I wanted to play with Astropad (I've long craved a Wacom Cintiq but lack the artistic prowess to justify one!)
My personal opinions (others are welcome to differ) would be:
1. if you're mainly working at a desk or don't mind using a laptop on your lap, use a laptop.
2. If you're thinking of adding a 'keyboard cover' don't - get a laptop: I bought a third-party keyboard cover for my iPad 3 - net result, using the keyboard with an OS designed for touch-only was a mess and the bulky cover got in the way of handheld use. I might, however, give the smart keyboard (or a third-party equivalent) a chance if it snaps on/off magnetically like the old smart cover.
3. If you want something for use 'on the road' get a large-screen phone: the 5" screen in your pocket is more use than the 10" screen in your bag across the aisle, and why have two cellular data plans?
4. If you want an eBook reader (for reading novels & suchlike) get an eInk-based reader.
5. If you've got all that sorted out and still have spare cash, get a tablet: there
are things they are good for, and for some people they can be laptop
alternatives (but not necessarily
replacements) but they're rarely a must have.
6. If you
only want an iPad for drawing using the Pencil/Astropad and have deep pockets, consider the iPad Pro 12" (First impressions of using the Pencil and Astropad on the 9.7 is that more screen area would be good) but be aware that it's going to be less suited to handheld use than the 9.7
