Yah, and the Mits has a different type of sharpness, when the keystone distorts the sharpness, it is fairly even, the light is still tight, the distortion is just a sort of tight bolded effect.
With LCD, you get a different type of distortion from the get-go, a more fuzzy text effect where the colors aren't lined up.
Now people run from keystone because they hear a loss of 1:1 pixel resolution, and I do understand that to a degree as a loss in resolution sounds pretty scary. You don't want keystone if you can avoid it, but it certainly doesn't make a huge difference in small increments.
The issue is the slight loss in resolution is actually often less noticeable than large convergence errors, because the Mits distortion from keystone is very even and predictable. That said, I'm not sure all keystone correction is as good as the Mits, it sounds like from some peoples' experiences, the Mits is better than some other projectors at this, not sure why, but I have some theories (as I always do...).
The more time I spend in forums, the less I want to go on about other people's projector choices, but on this I have to say the 8350 isn't a bad projector, but it can't match the hc4000 in terms of POP and even contrast in most scenes. The sharpness is just a third-added bonus.
Some people will still have to go with the Epson for the lens shift, so don't fret, most of you wouldn't think the difference was that huge, and it still produces a nice image.
