Just had my first encounter with the new system and honestly it took maybe 20% longer. The wait betwean screens was maybe 2 or 3 seconds, and there was one extra screen to select debit when the old system defaults to debit. Very smooth and painless and quick.
I also just had my first encounter. The CSR at the cust service desk mentioned they just got a new system and it wasn't too bad. A little confusion at first, but we figured it out. She even turned the screen toward me to show that it asked the customer to swipe RB (instead of her), but I don't remember step-by-step of what happened. I know after she entered K8, K8, she had to enter the total load amount ($1000), then the amount of each load ($500) before I made my first swipe. When asked if I was loading the full amount, I entered "yes" (other people have entered "no"). She then entered $500 for the 2nd load and I repeated the process.
One of the wikis I've read stated that the CSR enters $500 AFTER I swipe my GC. That wasn't my experience yesterday. She definitely entered $500 before my first swipe.
