Lyric Suite, feel free to check out some of my older posts, there's a 'debate' in one on the exact same subject and it comes up a lot here especially from people I assume (like you and I ) that are linux newbs coming from windows ?
The best I can tell you is to look into the reasons WHY linux is set up the way it is and why you don't have root permissions 'as standard' and then you may appreciate why they do it this way - Have a read of this thread viewtopic.php?f=90&t=74528
and especially the post by Thethistleweb, he really explains it clearly, as did another poster in a previous thread of mine.
I'll agree that it does 'seem' annoying at first, like you're being 'nanny'd' but . . .. there are settings that can be changed to make it so there are less password
inputs to the point where i only put my pass in to log in, and then to make changes, install software etc, it's not THAT often and you get used to it, that may not be what you want to hear but in reality it does make the best sense, and I never thought I'd type that lol
Plus as a 'newb' it's likely to protect you from yourself while you're still learning! I've lost count of the installs i've done through cocking the system up thinking i knew what i was doing, it's a lot different (thankfully) and a learning curve coming from windows, but it's actually in place for your own good, and not in a nannying way when you understand the difference of having root ownership and it being a separate entity, now i wouldn't have it any other way, and I understand better why my mate's always phoning me up to go and look at his Vista laptop . . . . . .
A lot of people post the same question when they first come here and it's not surprising, understanding why it is set up this way takes a lot of patience at first which I think some of the regular posters that have been on linux for years forget when they're answering 'newbs' but they do have the best intentions, they're used to it, we're not, it's easy to forget how difficult it can be making the migration.
When you realise that there are actually real advantages in this setup and why, will you appreciate how well thought out this operating system really is in terms of the way it 'looks after you' and the freedom it gives you, and how customisable it is, but all that only comes with experience, stick with it for now and in a few months time it will become second nature hopefully. I've had loads of fun learning so far and loads of frustrations but I kind of knew that was going to be the case before i started.
Being 'root' isn't all it's cracked up to be believe me lol . . . . It will cause you more problems than it's worth when you're learning, I know this from experience, maybe it was me, maybe not . . . . I'll tell you when I've found out . . . .
