I'm told the installation goes rather quickly from the App store, unless you have a slooow connection to the net.
Define "slooow", I understand the download is in the order of 4-5GB, correct?

So ~2 minutes for 100MB, that's nearly 2 hours of watching a progress bar for me. No thank-you.
Why the resistance to registering?
Why should I? I don't need to register with Canonical to download Ubuntu do I? Canonical charge me the same amount as what Apple are for updates too I might add.
Furthermore, in this age of company's customer data being tapped, why should I expose myself needlessly? Life's too short to be filling out registration forms and waiting for confirmation emails, just give me the goddamn URL and I'll be on my way.
What, the links at https://support.apple.com/downloads/ aren't good enough for you?
Care to point out the one that gives you the full OS and not just an incremental update? Looks to me the downloads there for OS X 10.10 require you to have OS X 10.10 installed in the first place. Or is there one I missed that updates OS X 10.6→ 10.10?
