Trying to find a low to moderate cost tablet 8 - 10" that will work with square. Most of the product descriptions don't say if the audio out jack is headphone (3 connections for output only) or headset (4 connections for output and microphone) - many just say "yes" or "1" for the audio out indicating it has 1 jack but not what kind of jack. The square needs a microphone input. I went to a chain store and asked and was told that most all the tablets should work - I have done a bit more checking and this is not true. Many of them have headphone only. Any suggestions for tablets that have the microphone input? Is it reasonable to get one for under around $150? I don't need a lot of other bells and whistles and prefer Android. It does need to have GPS which seems to be pretty common so don't think that will be an issue. I can use my phone as a hot spot so don't need cell connection for internet.
