Re: Ubuntu?
If all we need is a distribution that boots direct into Gnome 2 for that much-like-XP experience, then it already exists, and Linux will conquer (not the Ubuntu flavour, though).
The block is Microsoft data-format lock-in. Openoffice and LibreOffice are not entirely compatible with MS Office, and the (slight!) incompatibilities are the reason that businesses continue to fork out several hundred quid per employee on MS office licenses, than loading one of the free Office softwares onto their Microsoft systems and then planning an exodus to Linux.
It's not just Office, of course. Outlook is another lock-in. Ever tried using Thunderbird as a mail client in an organisation that uses Outlook calendar functions? Then there are Access databases. And of course, all the proprietary Microsoft-only applications that they've bought from third-party vendors.
Truth be told, LInux lost the corporate desktop before Linux was born. The only business that can easily migrate to Linux for everything, is one that has yet to buy its first computers. And the trouble is that start-up businesses usually don't have anyone who knows about Linux and about the Microsoft data-format lock-in trap. By the time they are big enough to have even a part-time computer system manager, Microsoft will rule their roost.
The unhappy face should be crying. The business model that Microsoft uses is very similar to that of a Cocaine cartel (albeit legal). By the time the user realizes Cocaine (or MS software) is not his friend, it's too late for most users to do anything about it.
