Lots of bag manufacturers/designers are making "speedy-influenced" bags this season. Satchels are just huge and the Speedy is one of the nicest satchel out there. As for the bag you're eyeing, the shape is nice and the fabric seems ok.
But, I don't like it that much. Honestly, it looks a bit cheap and you'd be limited in what you could wear with it what with the pattern and color. I think there'd be a better option out there for just a hair more in cost.
