My current tablet is an HP Slate 7 4200us. It's a factory refurb of an older HP Slate 7 model. (HP is currently pushing the Slate 8.)
It has a 1.3ghz quad-core nVidia Tegra processor, 1280x800 7" screen, 1GB RAM, 8GB flash, a 5MP rear facing camera and a 1MP front facing camera, Wifi, Bluetooth, and an SDXC slot for a microSD card to add additional storage. 5GB of the 8GB flash are available for app storage, so there's plenty of headroom to install stuff.
It includes ES File Explorer, Kingsoft Office, Google Play Books, Music, Newstand and Video apps and a few other things built in as system apps. It runs Android 4.3 Jellybean. It was obvious intended for games and video, but that's not my use case. I rooted it with Kingo Root and disabled various of the system apps. (I don't use the Google Play media apps.)
My primary usage is eBook viewer, using the open source FBReader for Android viewer app, and my eBook library lives on a microSD card. I also have a few videos and music files. I use a case with integrated keyboard that connects via cable to the microUSB port, and can do email, web browsing, and handle basic productivity taks like Word documents and Excel spreadsheets. While I don't normally use it that way, it can replace a laptop when traveling.
Performance is adequate, and the screen is gorgeous.
The main drawback is that HP is not offering OS upgrades for this model, and it's stuck at Jellybean. This is not a problem here. I have perhaps two apps that require a more recent Android version, and neither are apps I must have to work.
The good part is that it cost me $50, and is currently on sale at Micro Center, the retailer where I got it, for $40. If you don't insist on latest and greatest, it's well worth a look.
