i think it looks cool. and for nice leather, the price isnt bad. remember apple charges $100 for a little iPod case!!!
the only concern I would have with the case is the MBP overheating. part of the design of the MBP is to let heat dissipate using the aluminum case. so if you wrap the case in leather (even leaving the fan vents open) will trap more heat than intended. this might only cause your fan to kick on more than normal, but if you consistently run high processor intense applications, this could be potentially damaging for the MBP. although if you only use the MBP for web surfing, word documents etc, i would imagine everything would be OK.
