The iPad's popularity is the reason no one else is really in the tablet market anymore. Every OEM was pushing out a tablet in every size about a month ago but failed to make any decent amount of sales to stay relevant.
The Android space is getting more varied again in recent years but I really wouldn't recommend one to an average user over an iPad.
