Suggestion On Improving Ubuntu Linux

I've been using Linux for years now, and I find it a good or best alternative to “the” other OS. Every release of Ubuntu gives me the impression that it gets getting better with features that is essential keeping up with the latest trends in computing. What I find awkward in Operating Systems is that once you start your computer, it boots first then you type in your username and password, then the desktop manager loads last. The problem with this is the system loads its programs like networking BEFORE you type in your username and password, and I think can be a security issue. What I think is a better approach is once you start your computer, it gets your login first then boots the OS until the desktop manager loads, this way the programs loads after the security log-in, and it's more convenient since you won't be waiting for it to boot first then typing your log-in info then wait for the graphical desktop.

What do you think?
