Simply Asus, I think Asus is very sustainable and very reliable I have the Asus Nexus 7 #Loveofmylife also I have never had a problem with any of the hardware
I will use tablet for: reading news, watching short videos and sometimes long movies, listening music, playing games (asphalt 8), watching photos gallery.
If it's 10" size and a tight budget that you want, I'd recommend the Acer Switch over the Asus T100. If you can afford the Lenovo, get it!!! We're talking the 11.6" right? It's got a much better keyboard and it's just built better. Plus the bigger screen.
I just read you're looking at the 10 for the Lenovo. I'd still take that over the Asus.
