I find the problem with most of the open source UI's out there is the lack of good search capabilities. It is just so easy to open up gmail and search for a document. Everything else that uses imap seems slow and old.

I have not interacted with Square at all... not in any store or online presence that I have seen.... Where are they?

I seem to think that they are used by smaller or personal organisations (that's what I think they would be ideal for anyway). So maybe a lot of trades-people and freelances could be utilising their service.

Does anyone know why I should not use stripe as compared to Braintree, etc.? Is there a fundamental issue, that I have missed, or is most of the discussion surrounding price and volume.... as it stands, it seems like a no-brainer to use stripe for any new projects.
