[Closed] Bag question

Bit of a random one... I have an old (7yrs+) Crumpler Seedy Three which is still going pretty strong. I've taken it all over the world, slid across 20m of tarmac on it at speed and generally abused it; but it doesn't look the smartest.

For work/ general laptop duty I have a Pakuma that's a couple of years old, but tbh it's not aged well - it looks a bit scruffy now.
So I want something new for work - laptop/ A4 file carryable, but still usable on a bike, that won't need to be replaced in a year's time.
Is Crumpler the way forward (even though every wannabe Hoxton numpty now has one), or is it worth checking out Timbuk2 or any other brands?
