Basically meaning the main device people use to do simple tasks as surfing the web, playing a mobile game, checking bank statement, writing product reviews, and emailing?
I have an iPad 4 I bought right when it came out.
It hasn't been out of my bathroom for years where I use it for light gaming. Sometimes it goes weeks without being charged after the battery dies and i don't miss it at all. It's probably the tech purchase I regret most. I find it clunky and cumbersome to try and do anything. Everything is a compromise on it it in the name of a limited interface. Last few vacations I took, the cMBP came with, and the iPad stayed home because it wasn't worth the bulk for the limited usability. For example, on vacation I load all my pics onto the MBP as a backup each evening and pre-sort then while relaxing. iPad just has zero utility. I can easily fill the Macbook with movies ripped from my DVD collection and play them in VLC throughout my trip. The iPad has neither the storage space needed or the ability to use any decent codecs, so the iPad is that much more work to transcode the movies into something it can use.
I don't see myself ever buying another tablet of any sort they are just too clunky which is inherent to the design of nothing but a small touch screen as the US. If my computer died today I'd have a new one by tomorrow and sadly (very sadly actually), it wouldn't be a Mac because Apple just doesn't sell anything worth buying in that space anymore.
