Just to inject some reality back into the hype that's being bandied about...
1. O1 - it's a tool steel, and not the best one out there. It's certainly not magical, but it's cheap to buy and readily available. Corrosion resistance is well known (it isn't great). Edge holding is well known (very good) except for when it's over hardened. Some people have reported losing their edge while the knife sat in the sheath... but that's a problem with 01, not the construction.
2. Hard Chrome - while it's very nice for abrasion resistance, it sucks for corrosion resistance and sure isn't "tactical." Unless you believe tactical means semi reflective bright grey knives. Despite all the claims otherwise, it's been proven that hard chrome does indeed have capillary action, drawing the water up into it.
3. Handles - they are G10. Don't buy into the hype that they are some super secret proprietary composite, because they aren't. Just simple G10. Ergonomics are great, it's electrically isolated, and the G10 is tough, but it's nothing more magical than G10. Besides all that, they are pretty much the only thing I don't really have an issue with - the handles are close to perfection.
4. Tang - it's a big full tang alright. I haven't heard of any tang failures, other than the glue being used to hold it in failing. Again, something readily fixed by a slight change in construction, totally ignored by the maker. Change it so that there is mechanical lockup, and the knife would be fine.
RE: the epoxy "rivet" arguement, if that works so well, then there shouldn't be a problem machining a .125" slot into the side of the blade and interior of the handle so that the epoxy forms a brace stoping any possible movement. As is, if there is an epoxy / handle bonding failure, the knife will slide right out.
5. Kydex sheaths - good construction, though why they are grey is beyond me. Some of the better examples of kydex work out there from a semi-production shop, but there's still room for improvement here as well - like offering different options for attachment instead of 1 seatbelt webbing fits all.
6. Warranty, repair, etc. Do some research - best of luck. As long as you are the first owner, and haven't "abused" the knife (the definition of which changes as needed), then you probably aren't going to have problems getting it repaired. Then again, you probably aren't going to need it repaired.
In summation, they are good knives with a lot of room for improvement. Improvements of the steel, tang construction, and coating would make it hard to beat, and worth every penny. For example, a D2 or A2 ATAK with Black TiAlN coating and a tang with mechanical (as well as glue) lockups and a black Kydex sheath would be well worth the $350 price tag - I wouldn't hesitate to hand over cash for it.
