I just left best buy. The screens are Identical, I use the xoom on low or auto brightness, and it looks great. However moving thru home screens and apps button seem a little smoother on acer. But I I do have a decent amount of apps and atleast 10gigs of movies and music on the xoom.( I'm I making excuses) . The xoom feels lighter but the USB port and working SD slot make the Acer attractive. I feel the xoom should have quicker updates due to pure android experience. I'm thinking more support for xoom so I'm not return just yet. 17 days best buy gave me 30.
