everything from UI to installation to drivers.
So you just generally hate Linux then.
BeOS is an old OS and you are confusing Ubuntu as being Linux. When it comes to UI there are many ways of configuring how a Linux system looks and feels and BeOS themes are available for all of the major desktop environments just in case you really do want to make it look like BeOS (or MacOS if you have designer spectacles). Plus the levels of configuration available mean you could make it look and feel like pretty much anything else.
As for installation, there are many Linux distros which are very easy to install and far quicker than Windows too.
Driver wise things are NOT hard. Virtually all drivers are built into the kernel rather than requiring any installation and no OS can match Linux for the amount of hardware supported. The only complications are propreitary drivers for graphics cards but this does not have to be hard either. Most distros have some easy way of installing these drivers. On Arch Linux all I have to do is:
pacman -S nvidia
It then lists the packages to be installed, download size and disk space required. I press 'y' to confirm and it does the rest. Far easier than the Windows way of having to manually go to a website, click through half a million links, download 300Mb (300Mb for a driver?!? Windows is mad!!!) without any idea if it'll work or not, then run it, it unpacks some stuff somewhere on the disk without clearing up after itself, you then have to read through window after window of things that aren't really important and intermittently clicking a few options to deselent things that you do NOT want. In what way is my Linux experience any harder than Windows for drivers?
i know that linux has far more drivers but if beos had the drivers it just works.
This is silly. When Linux has the drivers it also just works. Good luck finding modern hardware which 'just works' in BeOS.
being more responsive is a plus.
I use Arch Linux and run a KDE desktop environment. There are very few reasons why I would want anything else.
