I'd rather AMD take their time and do it right, as opposed to rushing it out, riddled with security holes like that other company.
Not my intention to defend that other company but this is what happens when you sit on one platform/architecture for too long and artificially hold back progress - if you look at most older hardware things like memory protection and so on get cracked eventually hence emulators, etc. and people don't talk about them (generally) as riddled with security holes.
Same happens with a lot of things like routers and other network hardware - stuff that was considered having robust security in its day often requires a shower of patches if it is still in general use 10 years on.
