Last February, I bought a Nexus 7 thinking it would be a nice iPad alternative, i was wrong. Like many have mentioned, there are just too many apps on the Android side that STILL as of today, have only a phone version and no tablet version.
It took me four months to get tired of that Nexus 7 and buy an actual iPad. I then bought a Retina Mini in December and since then, I have not touched that Nexus 7.
too me, nothing beats the iPad experience.
