No easy way is different to no way at all.
Verified boot and pulling new stock images relies on trust mechanisms, which are increasingly coming under attack. People have already taken pops at Google to get into Gmail. I'd be very surprised if they didn't think the Android and Chrome infrastructures weren't good targets.
Also those are some of the big security features in Windows 8... so chances are that attackers are already working on ways to defeat them.
The sunny side is that those sort of attacks are incredibly sophisticated and are still very rare. And they could hit every and any major OS, application, service provider, etc, and there is nothing a consumer can do about it - so it shouldn't factor into whether to buy a product or not.(Bollocks... sobered up... Strongbow from the fridge will fix this!)
