If you find the X100 and X10 "riddled with problems and bugs", you might just not share Fuji's philosophy of how a camera is supposed to work. The only enduring problem the X100 had was the sticky aperture blades, which was very serious for those afflicted. Hopefully, they have that worked out. Other than that, people complain about slow auto focus, but I find it perfectly acceptable. No, its not as fast as the current round of m43 cameras or the new Nikon 1 series or any DSLR and if that's your standard of comparison, its slow. But I don't find that to be a bug - it forces a different approach to shooting that I personally love. The X100 is supposed to be a cheap Leica, no - the best of which don't even offer auto focus... Other than that, I'd sort of like it if they'd change the ISO menu a bit, but that hasn't really been an issue and I basically love the X100. It has a few quirks, but they've just become part of the charm of the camera. No serious problems or bugs other than the SAB issue.
And the X10??? It has white orbs. Which some people have found occasionally. Many have not and many more may have but would never notice. I've found one of my shots with them (out of a couple thousand), but had to look REALLY hard to figure out that's what I was seeing and they don't hurt the shot. I consider it a minor problem that will be great if they can fix, but not even remotely close to a deal-breaker if they don't. Other than that, a few complaints here and there, about the same as with any other camera, but not even close to riddled with problems and bugs!
I think most of the people getting hysterical about these cameras just fundamentally don't like them. That's fine. I personally wouldn't like the X100 as an only camera - I like to shoot in ways its not conducive to a lot of the time. But I also LOVE to shoot with it in the ways it IS conducive too and would say its probably my favorite camera, if my least versatile and athletic. It took me a little longer than most cameras to really learn but once I did I haven't had a single problem with it. Neither of these cameras are perfect, but I think the "flaws" are greatly overblown by folks who were expecting something different than what these cameras offer.
BUT.... the character of the X100, as much as I love it, is NOT what I'd want in my primary, everyday, camera or system. Which is why I have a bit of trouble seeing it replacing any of my m43 gear, which also has tradeoffs, but which falls really easily into that role for me...
