Did I downgrade or upgrade my Palm Treo?

Its day 3 with my Palm Centro Unlocked GSM Smart Phone
on the road, nearly 200 miles away from home. How I switched from the Treo 650 to the Centro? My cell phone provider’s equipment insurance program. Since they are not producing the 650 anymore, I received a candy apple red Centro. I’m getting over the shock of the smaller keyboard. On the other hand , its stylish, and it can still get down to business. After doing some research by visiting the Palm Blog regarding getting more out of the Centro and also by getting used to the phone and seeing the new Palm applications, I did decide that it was a upgrade in small package.
