Buy it. Run it. Your players will love you for it.
I ran it for the first time yesterday to a group of players with heavy experience with DnD (OE through 4.0 edition players), White Wolf (currently in a crossover game with them based in NWoD, but everyone started in OWoD, and also play Exalted and Scion with them), Rifts, Champions...heck, most systems. All four players were floored by the game and have completely bought in. The most difficult to please/discerning player stated it very well might be her favorite system.
I found it to have a great ease of flow to the game. Fate points help you out in so many ways, its not even funny. Players were trying to find ways to compel themselves to get more of them.
The rules aren't very crunchy (though magic is somewhat complicated), but they have enough meat on them to make a good game. Having said that, we screwed up several rules yesterday during play. The more we play it, the better I expect the experience to be, but even screwing things up it was a lot of fun.
I suggest going out and listening to some of the many podcasts that are out there that have actual game play. It is a fun, collaborative system, well worth the purchase.
