I need help choosing from some android based tablets. This will replace an iPad and be used for some movie streaming, some picture viewing, and mostly Internet. My choices are: 1. Nexus 10. Older but cheaper than the other options, I wonder how it stands against todays tablets. 2. Galaxy Tab Pro 10.1 3. Lenovo Yoga 10 HD+ 4. Sony Xperia Z2 tablet I would like to know how these compare to each other with regards to screen quality, sound, speed, power and such. A camera is unimportant to me on a tablet. I might consider an iPad air or even a windows tablet also. Any help with these choices is very welcome and appreciated. Thank you!!
