No worries about questions -- that's why we're here.
So, let me go through a few things:
1. Which do I like more?
I like the big GNP 12.2 over the GTS 8.4, mainly because of size. I can use the smallest fonts on the GNP and everything on screen is still plenty big enough -- I can finally use some of that extra resolution to see more of a "full screen" like a normal computer monitor. It's really a difference compared to smaller tablets -- for the first time, I don't feel that I'm seeing a "squished" version of everything.
No doubt that the GNP is a gigantic monster -- I don't feel that it's really heavier or anything like that, but it's kind of a shock just to handle the thing -- I figure it might save my life if I'm ever in one of those mass shooting things, as I could use it as a shield. ;-)
I expect I'll get used to it over time, but in the meantime, it's just very, very nice. It will still fit into any of my bags that would fit a normal notebook computer, though I suppose I'll run into some "iPad pockets" that it won't fit into.
The GTS is a very nice little machine, though -- that screen is really just absolutely amazing. Though, as I said, it really is at least a bit over-saturated, but boy does it make pictures look great. Still, pictures are no slouch on the big GNP.
In the end, I've got a GNP LTE with a data plan, so I can travel with it and have service, so that's what I want -- something big enough to see maps on, and so on. I'm pretty happy with it.
2. What do I use them for?
Well, as I said above, I've got the GNP LTE with a data plan, so that goes with me everywhere I go. I mainly use it for e-mail, web browsing, media playing, and a bit of document viewing. The GTS is really just "excess baggage" around the house -- it might become more of a "big media player" more than anything else, while I use the big GNP for other stuff.
3. Do I find the 12.2-inch tablet too big to carry?
Not really at all, like I mentioned above. I've always got either a soft briefcase-style bag that can hold my gadgets and camera equipment, or a backpack that can do the same, if that's what I need -- and the GNP will fit into either with ease. The only time the GNP feels a bit "too big" is when I handle it, and it's just odd to be handling something that big. But, I expect I'll get over that, and it will feel "natural" in pretty short order.
4. Any previous tablets?
I just have the GNP and the GTS now, though I've gone through a few other things. I actually bailed out of an iPad Air to go for the GNP -- I got the iPad back in January 2014, and the only "big" Samsung tablet that AT&T had (I was going to stick with them) was the Galaxy Tab 2 10.1 -- there was no way I was going to depend on that old thing. Which is the only thing they had for what seemed to be three or four years. ;-)
So, I got the iPad, instead. A nice piece of equipment, but I think iTunes is just the most horrendous piece of garbage software program I've ever encountered, and using the iPad for much beyond e-mail and Internet (i.e., like "documents" was just too much iTunes hassle to be worth even trying. So, I sold the iPad and got the GNP. And now I can EASILY do EVERYTHING I want to do with a tablet. What a concept.
I've also had the original Galaxy Note 10.1, the Galaxy Note 10.1 2014, the Galaxy Tab 3 8.0, and the Galaxy Tab 7.7 -- with the AMOLED screen, the predecessor to the new Galaxy Tab S models. I'm definitely happier with the two I have now over all of the older stuff.
5. Is the 12.2 good for media?
Oh, you bet. I see the GNP as being "better" for pictures, without the too-saturated colors, though there's still plenty of high-resolution goodness to make them look very impressive. And size makes them look good, too.
The same goes for videos -- the difference between videos on the big screen compared to the 8.4-inch screen is simply amazing. VERY nice.
As for music, I'm happy with it -- I've read a review on gsmarena.com that mentioned how it had very good, clean sound output, which is more than I'll be able to hear or measure myself. I use my tablets with the Bose SoundLink III speaker, and I'm very happy with the sound. I also have the SoundLink Mini, which is utterly AMAZING for such a small speaker -- I recommend both of these highly.
I think that covers everything -- and I hope it helps. Good luck with the hunt!
