I can't imagine a world where the unsophisticated "consumer who wants a solid, fast browser that just works" doesn't just use the default browser that comes bundled with the OS. Safari and IE are more than capable to fill that role these days.

Some of those unsophisticated consumers are still using Windows XP (or Android Gingerbread or ...).

To clarify, the theory is that there is a significant market in people who are still using XP, are sophisticated enough to want a 'better' browser, have knowledge and IT permissions to install one, yet at the same time don't want a featured interface.

I'm sure there's a few people like that, but a market big enough to model your product around them? I.... I just can't imagine that being the case.
