That's all well and good, but at what point in time has Sun shown even the slightest inclination to target the non-technical desktop?
Because people in companies (shock, horror) actually have to do some administration with their desktops. They can't have the amount of work it takes to install Solaris, nor the things that have actually gone wrong with it. Of course, the natural reaction of Sun is for you to call in a Sun engineer, but I'm afraid they'll find that people simply won't do that for desktops, and they're increasingly not doing it for servers either.
It's become clear over the years that Sun makes their stuff less than perfect to install and administer, and less than intuitive, so that people have ended up calling out their Sun engineer and paying for all the paraphenalia that comes with it. Those days are over.
