I purchased a tab for use in my grad work. It's worth it alone just being able to sift through the hundred of pages of articles, highlighting or annotating what I need, while I work to construct my research proposal.
I've found myself using it quite a bit to stream video on my home network (watching meh some star trek, whenever I'm washing dishes/cooking dinner hahah)
It's my first real tablet, a galaxy note 8 that I got last year. It's definitely been worth it. The use of writing with its stylus is very nice and accurate if you have even marginally neat writing. However, it's best to write on it with the tablet in landscape mode - don't try to sit back and write on it like it's a notepad in an awkward position... It's much more receptive when you place your hand onto it in the most comfortable way possible for your wrist and side of your palm, just as if you were writing a letter on a desk with paper. I imagine most stylus pens with limited screen space may behave similarly.
Much like phones, I guess it's convenient to view my email on a mobile or tablet. Since I have no phone, I use my tablet more so to check on such things.
I believe at first if you were to get one, you may not find quite so many uses right at once. But give it a few weeks and you'll find yourself consistently reaching for it for tasks that otherwise would've been time consuming to check up on prior. I love being able to dictate to the tablet, whether it's a web search, note taking, etc
I don't really game on them. Mobile games tend to bore the living ***** out of me
Recording class meetings is a convenience. I'd be better off with an actual field recorder tho.
Goes double as a car navigator if you choose a model with gps. Sygic has been good to me
I've used it while traveling in Morocco and the US, their maps are well detailed enough if used for driving nav. Since GIS is my forte, I appreciate the use of gps to make my tracks and poi's for some lite-gis data cap. I would be wary of tablets in metal casing if you choose to go for a gps enabled unit. My father went for the transformer primes when they released and the gps is horrible with its casing type... but my galaxy note is excellent given its plastic housing (which doesn't feel all too cheap, in fact I appreciate how light it becomes in turn. Plus most put their tabs in a case anyways).
Mobile app shopping, is usually kinda meh for me... I prefer just going onto the full website most of the time.Edited by redoubt9000 - 3/1/14 at 8:48pm
