I am starting to like my A500 more now that I got my dropped wifi issue fixed for now. I believe my router was mishandling the connection, the more I read about my DIR-655 router.
As far as I understand, the only diff between the a501 and a500 is the 3G capability. I also do what chismay does and tether my a500 tablet to my phone (Galaxy Nexus) and use it's 3G connection. Great for AudioGalaxy app so I can stream music right off my home HDD, and watch YouTube vids in my truck on the go, while I leave my phone in the 12 V charging mount for calls.
Good idea with the 32 GB card as well.
