Trialled it when it first came out and thought it was woeful. It seemed, to me, to be an unfinished product and released far too early in a cynical ploy to gain a presence in cloud accounting. At the time I used it the software couldn't produce an aged debtors or creditors report. From memory there wasn't even the option to export the data which is the least I'd expect.

I notice the Sage One website used a Mac Air, if that's a market they're hoping to tap into, they'd be far better off employing a Mac programmer.

Perhaps it's moved on now as at the time Sage where promising new features.
