This is for the 10" coby. I got it to replace the functions of an e-ink kindle. I wanted to be able to read books, surf some simple web pages, maybe check my e-mail and calendar, play some simple games. I liked the idea of a bigger screen that I could see page-size pdf (and maybe a comic book) on. It turns out that this tablet is fine for those needs.
It actually seems made pretty well. The touch screen seems to work well - by way of comparison, I've had a couple of older tablet pc's, and older windows ce pda's, my wife has an older resistive touch 7" android, I have an android phone. So on the one hand I've used a lot of touch screens, on the other, I can remember when you had to have a proprietary batter-powered stylus to use one. So to me, the touch screen seems pretty good, but I don't know how that will translate to others. It is a finger print magnet and picks up smudges like mad. It is perfectly adequate for e-book reading and playing simple android games.
I am an average sized male and the size is fine for me for a big book reader. The trade off of the bigger screen is that you have a bigger device to hold. I can just "palm" it with one hand - it is 16 X 9 so it seems longer than it does wide. I don't think it is too large to be a comfortable reader.
The wi-fi connected in a snap, couldn't be easier. One thing that is sort of annoying is that everytime I resume from a suspend I have to disconnect and reconnect the wi-fi for it to connect. I haven't figured a way around that yet, but I think it may be an ice cream sandwich "feature." It connects easily to our linux computers with the cable.
I found that I was more bugged by the lack of google play marketplace than I thought I'd be. As best I can tell, everyone who has tried rooting the 10" has bricked it. So I didn't root it. You can get the apk for google play easy enough and side load it, but the device isn't on google's list of approved devices so the apk won't run and connect to the market. Because you can't root it, you can't edit the boot file to spoof it as a device on google's list. So unless you root it or google adds it you won't be connecting to google play.
Which isn't really that big of a deal. It has a get jar market on it, but I had already put on amazon market before I bothered looking at it, and there's really not much use in it. The amazon market is easy enough for anyone to add - just point the web browser to amazon and follow the directions. Of all things, the only thing I wanted to put on it so far but wasn't able to yet is tux math for the kids - it is on google play but not amazon market and I can't find the apk on the web. It was easy enough to side load other apks. It runs the angry birds apps fine, and the cut the ropes, fruit ninjas, temple runs. I had a devil of a time getting where's my water/Perry to install. It just wouldn't install. I tried different versions and nothing, then one time I tried it for a lark and both just installed and now they play fine. I must have installed something with a needed library or something along the way. Who knows. I downloaded free solitaire and freecell from amazon and they work fine. That's enough games for me, so I haven't bothered putting any emulators on it, without hardware buttons I don't care to.
It has both a regular size usb and a micro usb, which is nice because you can use something like a usb key board. The power plug is an additional little port. The batteries last longer than I thought they would - good enough for me to read and play some games. I put some videos on there just to see them and they worked fine. The kids watched some youtube on it and that was fine. I couldn't get netflix to install on it though.
It has an micro sd card slot, that is important to me. The file structure is a little wonkey, but you'll find the sd card if you look around. After the first time it didn't really matter to me because it remembered the location in the history and I can just click the short cut there.
It comes with a book reader built in. I side loaded an epub file and it seemed to present it just fine. I went ahead and put the cool reader app on it because I like the flexibility of that app. I used it to read A Dance with Dragons an it was a good book reading experience - I turned off the background and just use white text on black or yellow on blue. Honestly I didn't miss e-ink and I was a fan of it.
It isn't an ipad and it isn't a tegra 3. It is $150 bucks. So if you want the ipad or a tegra 3 don't get this. If you have some basic android experience then this will seem familiar and easy, and if you want a basic tablet then this is a fine one. I got lucky here, it fits my needs very well - so if you are looking for something like that, book reader, web, simple games, with a bigger screen I'd recommend this to you.
