I just today received a "refurbished" 2009 mode Airport Extreme Base model #A1354l from Apple Store. However, it looks like it is brand new as it came in the original box, wrapping, etc. Does anyone know if this is the most current model? I was told that Apple just came out this week with an updated version. If this is true, then what is the difference from the one I just purchased? Also, have there been any problems noted with this base station? Thanks for your help.
