I kinda wonder if the Icon storage was supposed to be announced in line with a more direct semi-truck model of going after the pro shops. The price point for those puppies is way beyond the typical HF shopper, and while I've got zero issues with 25" depth (more would be crazy-big in my DIY garage - hell, I really like the 22" depth of my USG chest), I have to think they did it for a reason. Cost? Sturdiness? Some kind of research they haven't articulated?
I'm a marketing guy for a living, and it drives me crazy how much "What" (specs, etc.) there is in a lot of product stuff and damn little "Why". I think HF had to have a reason beyond just cost to choose that depth. Otherwise, I'm just adding 20% of their price and comparing it to the deal the truck guy is willing to give me, factoring that against the financing I probably already have with him, etc. (the truck guy doesn't talk to me in real life of course, so I have only a vague idea how all that works).
FWIW, my HF had the Icon stuff on display last year sometime, and I was pretty impressed - beefy, well-integrated power, cool power-tool drawer, etc. But I don't wrench for a living, and even with coupons they're just out of my league. My USG cart (which I like a lot) was under $300 (the 26"x22" single-bank - I also have their 5-drawer car) vs. $1600 for the 36"x25" cart), though the more-direct comparison would really be the $500 USG 44"x22" since its 14K cu.in. capacity capacity compares better to the 16k+ of the Icon. Even adjusting for the extra 15% of space the Icon has, the USG cost-of-space would put it under $600.
So while it's not strictly capacity discussion, their website isn't telling me much of a story...
