Yeah, I've been wandering around Amazon for about an hour scrolling through pages and pages of tablets. The problem is actually an over-abundance of options. I have never used a tablet before and it's just a bit overwhelming.
I went through the same thing late last year through early this year, reading everything I could from tech reviews to actual end user reviews, spec sheets, etc. It was mind-numbing.
Eventually, I settled on the 10.1" Samsung Galaxy Tab 32GB, and have been VERY happy with it in every way.
From the beginning, when I fired it up for the first time, put in my information, including my Google account information, and it automatically downloaded all the apps and everything I already owned onto the device, I was impressed and happy with it. No fuss, no muss, within a few minutes, this tablet looked like MY TABLET with all MY TOOLS on it already! That was awesome! It's probably true for other tablets, but still - I was impressed with that, and REAL glad I didn't have to go through some rigamarole to DL each thing I already owned separately.
As for my criteria that led me to this particular tablet...
First, photos had to look great on the screen. That was MUST for me, obviously. They do.
Second, the reviews had to be very positive. They were, and still are.
Third, I wanted something that would allow me to easily get stuff in and out of it via USB, and it does that. It takes a little Samsung to USB adapter that I carry with me in the watch pocket of my jeans, which is very inexpensive, and it works great. I can plug in any of my thumb drives, all the way up to my large 64 GB thumb drive, and move stuff back and forth or just use it as an extension of the tablet's memory, viewing or updating files directly on the thumb drive as long as it's plugged in. I also easily move stuff in and out of it via WiFi using
Dropbox. Both methods work great for me.
That same adapter allows me to tether my DSLRs to the tablet. Using an app called
DSLR Controller, that tether turns my 10" tablet screen into a big, beautiful live view screen that's so much better than the one on the back of the camera. I can also use it to review all the shots taken so far on the CF card in the camera.
The app allows me to control all kinds of camera functions, from shutter speed, ISO, aperture and so forth, to even focus by just pointing on the screen to what in the image you want to be in focus, and it works the lens, though I can still do all that from the camera as well - it doesn't take it over like a zombie, but the live view it displays renders the optical viewfinder on the camera useless, of course.
Obviously, this is the sort of thing that lends itself to tripod work, where you have your hands free to work with the tablet, but for some situations, it turns out to be ideal. One really great use I've found for it lately is shooting my DSLR through my microscope. Using the tethered tablet, I can see, adjust, focus and shoot straight from the tablet, then I can review directly on the tablet. Because it's in live view and remotely operated via the tether, there's no camera shake at all while shooting. It's a very slick setup.
In addition, I got a couple of docks for it. One I really don't use, and that's the one that just stands it up at an angle and allows the charger to be plugged into it. The other is a keyboard dock, which is the one I prefer. It holds the tablet upright on a table at a comfortable viewing angle, provides an actual keyboard for typing, and provides for the charger to be plugged in. While using the docks, you can plug in the charger, or you can plug in the USB adapter for the tether or thumb drives or what have you, but not both - it's all the same single port.
Neither dock is necessary for operation or charging, by the way.
While on the go, I un-dock and use a faux-leather portfolio style case to contain and protect it. It opens and folds back on itself to provide the support to stand the tablet up on a table for comfortable viewing and use.
As time goes on, I find myself using it for more and more stuff, especially stuff I used to use my smart phone for when on the go or just not sitting at one of my computers, like checking email, surfing the web, watching videos or listening to music (through plugged in ear buds sounds great), playing games, etc. As long as I can find a WiFi connection, which isn't difficult these days, I'm online and in business.
And I LOVE using it as a reader. I get and read books from Amazon on the Kindle Reader, Barnes and Noble on the Nook Reader, stuff from Google and PDFs on the
Aldiko Premium Reader and it's just fantastic having an entire library in a single little device like that. Plus, the e-books are cheaper than the paper versions, and arrive within a minute or two, instead of waiting for them to be shipped.
Then there are all of the apps/tools. DOF calculators and other little photographic calculator tools/apps are readily available, plus all kinds of other tool-type apps that I find useful for other endeavors having nothing to do with photography.
I've never used any other tablets, other than for a minute or two in stores to see how they feel in my hands, so I can't give a side by side apples to apples comparison for you, but I'm VERY happy with this one, and have ZERO buyer's remorse nor ever a thought like "gee, wish I'd gotten that other one instead".
At one point, I thought it went dead on me! I had let it totally run out of juice. It lasts me all day and night, for what I do, but I'd let it run a couple days without plugging in the charger. So I figured I just needed to charge it up. I plug in the charger, go to bed, and when I wake up, I go to fire it up - NOTHING. DEAD. Oh NOES!!!!!
So I get on the internet, run a Google search describing the problem, find that the solution is to hold down both the power and volume up buttons at the same time until it lights up, and you're good to go again. Worked like a charm, and I've had no other "issues" with it at all.
Hope you find something in there useful to you!
