Despite of many tries making hardware better there's no better routerboard than RB1000 from Mikrotik.
RB1000 still active, It's working for me now 3 years online, very good perfomance, no compatibility issues with another equipment.
RB1000 was built on Freescale CPU with built-in ethernet interfaces, no other cheap parts like atheros etc., just All-In-chip router with hardware encryption.
I think that today Mikrotik want to save manufacturing costs on cheap chinese chips
