As others have mentioned, the Stream 7 is an amazing value for the money. It's weird, but, when I fist powered it on and started using it, it was just a tad too sluggish, even taking into account the 1GB of RAM and the low workload that I placed on the processor. However, after going into the settings and installing all of the available updates, the device flies! I must say, this device is great! It's amazing how fast we've advanced technologically: full Windows in a $99 tablet.
There is 20GB of free space remaining, after the OS. Not to mention, it has a Micro SD card slot that can handle 128GB cards (when properly formatted), I believe. Battery life is great, too. For $99, you'd be hard-pressed to find a better value. As a fan of Android, there aren't many cheap Android tablets I can recommend. But, for someone that doesn't want/can't afford to spend much more, you won't find a better value for your money. HP definitely has a hit on its hands.
