A couple of posts ago I discussed the differences between the Google Android and Apple iOS models. One of the advantages of Google's model is that the software can be used by a number of manufacturers, resulting in inexpensive products.
I purchased a Q8 7-inch tablet with 8GB of memory and 800x480 pixels. The price was $39.95, but I discovered that I had a PayPal credit for $9.95, thus my total out-of-pocket price was $30.00. As a bonus I received a stylus (valued at $3.00).
There was no name brand on the box - anywhere! However, the tablet was packaged well. The battery was only partially charged, so the first step was allowing the battery to charge to 100%. The battery charges fast on this particular tablet. One feature I like about Android is that you can see which apps are contributing to battery usage. I discovered, for example, that Facebook was continually updated and utilizing 40% of the battery since the previous charge.
My Q8 is about the size of the iPad Mini (approximately 5x7 inches). I don't have an iPad Mini, but will sneak my Q8 into an Apple store and try to get a picture comparing the sizes.
If you are looking for an inexpensive tablet, either as a second screen or as a starter tablet for your children, definitely consider this one.
