The Mesquite tablet runs Android 4.1 on a 1.6 GHz Intel Atom Z2640 CPU with 1GB of RAM, Wifi, Bluetooth, and a VGA webcam. It also has 8GB of storage, a microSD card slot, and a single speaker on the back.
The 7" screen has a resolution of 1024 x 600, the same as on many other 7" tablets in this price range. The tablet measures 7.6" x 4.9" x 0.4", weighs about 13 oz, and is specced at 5 hours of battery life. This tablet was initially released on Black Friday at $89, but it is selling today at $99.
I bought one of these tablets on Black Friday, and while it's not the best tablet I have seen it's also not the worst. I plan to post a review this weekend, but for now I can say that the Mesquite tablet has a more polished hardware design than many of its no-name competition, though it lacks the HDMI port which is growing increasingly common on budget tablets.
The Mesquite is running a stock version of Android that is less polished than some sub-$100 tablets like the ones from Ematic. It also has unimpressive benchmark test results. That's not necessarily a strike against the tablet, but it's also not a point in its favor.
Please don't take the above as being unnecessarily negative; the HP Mesquite is still in the running for my choice for best value under $100.
