I got this for birthday (thank you mom, dad, sisters, love ya!) and want to chip in:
The bag is extremely well built; my father, totally uninterested in my dealings otherwise, said: thats a good bag.
I agree and expect to still have it 50 years from now.
The main reason for wanting this particular bag (except for it's stunning looks) is the inner measurements. This particular bag will fit a standard size IKEA lunchbox, which makes it perfect for commuting to work.
It's a bit on the heavy side for long walks if one fills it up to the brim, but quite manageable for travel. I had 3 bodies (M3, OM1, Nex3), 5 lenses, a flash and some misc. items packed for Christmas with some room to spare.
One downside with this bag is the carrying handle (not the strap), which has a piece of leather poorly fastened with velcro. I'm afraid of loosing this piece any day now, since it keeps falling off.
