If you are thinking about getting a great commuting bike with Shimano XT components that can do-it-all, the CELL X-2 is the best value high spec commuter available.
Don't wait to get yours, as industry wide bike prices are going up (yes, even us) 30% on the next shipment of bikes due to the U.S. Dollar.
The only choice for riders who are too strong for road bikes and too fast for mountain bikes!
The aluminium is good quality if it's as advertised, but the largest frame size is not for anyone who's even a bit taller then average (if you want the most efficient position and not ride with knees bent under a sharp angle)
