Not sure what UEFI is actually for...and why Windows is preinstalled
When I buy a new car, I have the choice between petrol, diesel and hybrid engines, and nobody is forcing me to buy the fuel from this or that oil company.
When I buy a new laptop, I usually have the choice between a 13, 15 or 17inch screen and between a 320GB or a 2TB disk. But Windows comes preinstalled, and I have to pay for it, although I don't want it.
Once Windows has booted up, I'm reminded incessantly that my laptop is suddenly very much at risk unless I pay for the full license of this pre-installed anti-malware software. Except I don't want that particular anti-malware software and my firewall is on my router already. I am also reminded to take out this Small Business Advantage (whatever that is), that online backup services (dunno what is backed up to where), and pay for the full MS Office license.
Depending on the browser I use I am reminded to use Google or Bing as my default search engine.
I then try to relax a bit by browsing on Youtube, where I am bombarded with advertisements for beer, some must have video game, and the latest bloke flick. During those videos suddenly half the screen is replaced with an advertisement rectangle because YouTube has warmly found out that I'm looking for love and I should join Mature Dating, because Russian women are waiting for me already.
Wow....this really beats any diesel engine in a car....
