At PMA in February 2010 Lowepro's Pro Runner series of backpacks and convertible rolling backpacks was first shown (they first showed pictures very early in January though). The backpacks are the 200 AW, 300 AW, 350 AW and 450 AW (the last two having space for a laptop - the latter is also considerably deeper than the others, fitting up to a pro DSLR). The rolling backpacks are the x350 AW and x450 AW.
I'm interested because the largest model (450 AW, the normal backpack) is a suitable alternative/upgrade for my CompuTrekker AW which is a bit heavy when fully loaded. The Pro Runner 350 and 450 has a padded waist belt (unlike the CompuTrekker, which just features an ordinary waist belt), which takes the load off your shoulders.

(P.S.: I now also consider Lowepro's flagship backpack, i.e. the Pro Trekker 600 AW).
