i'm not even much of a fan of ubuntu anymore because canonical wants to breathe down my neck all of a sudden.
if secure boot was a non-trash thing then i wouldn't have to make work arounds for it. i seriously dislike microsoft taking my entire system hostage because they want to control what i can and cannot boot.
and this is on top of the CPU clock being an absolute nightmare as well as the app store.
1. Typical users don't need to use Xubuntu or whatever other names they come up with for every dime-a-dozen variation of Linux. Just because Windows 8 doesn't suit your needs doesn't mean that it's bad for everyone. Since everything needs signatures, Microsoft has strived to try and reach out to developers of software to make sure as much legitimate software as possible is ready to use with Windows 8.
2. You don't have to use the store app. You don't have to use apps at all. If you're all up in arms about it, by all means, install things the classic way. Microsoft isn't trying to erase the desktop interface or anything.
3. Overclocking never was and never will be a manufacturer-supported dealing. Microsoft has no obligation to deal with your overclocking issues.
