No, as long as you're looking to buy something its manageble, but as soon as you have 10+ items you wish to sell, it becomes a disaster. :S
Perhaps i exaggerated the wording, but it is pretty damn bad and un-userfriendly compared to how it is in games like WoW, even more so if you're used to using auctioneer or other AHaddons from WoW.
You can argue that this is just released, and this isnt WoW, but a gamefeature like the AH, that people will use frequently in their everyday gameplay, needs to be better than this.
