Ebay app is better than ebay on the pc, just bought some batteries and was up against someone else. Received a message on the iphone like an sms that I had been outbid. The app menu is simplier than the pc version and more effective when bidding against someone else, this is because you have to confirm your bid and you see the clock ticking. Simplified search function, but in the simplistic menu you can see all the items you are bidding on, what you have won and lost. You can also pay using paypal and in a couple of clicks payment is made. Fantastic app, I may use the PC to search for an item in the future, but when a bid is made it can be easily followed and tracked on the iphone which I believe may give you edge against other bidders.
