A good amount of positives.
If you use stubhub and have a smart phone, you will obviously get the app, barely any need for reviews. I cant really think of any problems other than not being able to NOT specify the exact seats like on the desktop site. Fees will need to come down, or coupons dispensed to compete with Ticketmaster resale.
