I've been frequenting Fred Meyer, playing with the Nexus 7 day after day, and it seems like such an incredible device for a great price. I want it bad.

I've intentionally kept my self from buying it too soon to make sure that I investigate every last detail and make sure it can function in all the ways I need. There are two things that my decision is hinging upon. 1) I need to read music on it for a wedding band I play in. I emailed myself some attachments and i could see them -- not super clear, but I'm young with good eyes so I'm not worried. Check.

However, I did some research on the Square app for processing credit cards (I lead a band and we sell high volumes of merchandise), and it sounds like it's not compatible with the Square Card Reader. So then I did some more digging and with what limited information there is, it seems that the Nexus 7 is not compatible with any readers because of the headphone port. This is killing me. This is a very important feature and I don't want to be forced into buying the iPad, which for me is a bit too large and pricey.

Does anyone have any more detailed information about this? Will it work eventually? What is the limitation? Lack of a microphone port in the jack? I'm so saddened by this news.

Best,
Devon
