A friend gave me an iPad that is only 5 years old. You can only get apps from the apple store. All apps require OS 7 or 8. This iPad can only be upgraded to OS 5.7. I guess that is why Apple customers keep upgrading to the latest & greatest. They have to! Don't get hooked on Apple products.
For opinions on purchases try using Yahoo Answers. You can read questions posed by others on similar products and the answers they received - OR you can ask your own question and get answers from others who may have the products you're curious about. They can tell you of their experiences.
Just keep in mind that on any public forum you can get good answers and you can get totally ignorant answers as well. Be ready for the ignits.
