Coming off after my Eagle Creek Crossroads (rollaboard) gave up after 10years of service. Wheels destroyed from being dragged across continents, zipper coming unstitched in couple of places.... but thats about it. Bag still looks great otherwise! Telescoping mechanism of the handle still works fairly well (compared to American Tourister/ Samsonite - which start failing sooner).

Anyways... not a road warrior anymore but still would like a solid bag and decent looking (and not Tumi/ Rimowa price tag). TravelPro Platinum Elite sounds like the crew approved carry-on and budget friendlier as well (stacks with AMEX for a small discount)... USB thing looks pretty gimmicky and maybe adds some weight (is it useful?). Briggs and Riley Baseline hold better reputation, the backpack clip attachment is nice touch and the expansion mechanism looks helpful. My only downside with BR is the price tag... it's almost 2x of TravelPro.
LuggageWorks kindda appealed to me (just 'cos) but I don't think it's practical for a recreational traveler. Durable sure, but it's super-heavy.

In terms if design - I think, I'd like a spinner now. It's easier if Mrs CnO has to handle 2 bags on her own (and I am pre-occupied momentarily). Also, it would be nicer to have a laptop bag/ backpack attachment.... placing bag on top of the rollaboard makes it heavier and bag is always slipping to either side of the handle. Comfort and ease does become important as you get older, heh.
Also, mostly looking for domestic travel or North American continent. I understand EU and Asia have different standards with carry-ons and we will cross that bridge another time. Durability really helps since I do see end-up checking bags when hauling hiking gear or going on longer trips.

Btw, my last bag (Eagle Creek) was a recommendation from FTers :-) Hopefully next one runs equally solid!!
