update
Just to update my earlier comments for those who may search for info on compacts in the future, a couple of points:
1) Although the the old Nikons will stay as loaners, direct comparison to newer rev. porros bumps them down a notch, probably due to newer coating technology. They are a pain w/glasses, having rubber eyecups and little eye relief.
2) This is completely personal preference, but although I started my search for compacts with a "smaller is better" mindset, the optical quality plus price of decent rev. porros puts them head and shoulders above the compact roofs, for me, as a design. And in fact carrying a few around convinced me that, up to a point (e.g., the Yosemites were just a bit too big, despite their light weight), weight is as important as size (the Pentax Papilio, for example, weighs a bit over 10 oz, which feels a lot lighter than the 13.5 oz. of the E2 (the 12 oz. published weight is incorrect. I weighed mine).
3) There is, right now, nothing that satisfies what I'm looking for in image quality, weight, size and waterproofness, but the new generation Bushnell E2 Custom Compact is close. For my tastes, it was better than any of the small roof compacts out there in image characteristics, besting everything from the Nikon Premier 8x25, the Pentax SW 8x25, and the Leica, Zeiss and Swaro 8x20s, although for different reasons (sharper than the less expensive compacts, not sharper/brighter, but more user-friendly view than the alphas - I definitely prefer that expansive 3D porro image). If the E2 had a better diopter adjuster design, were waterproof, and returned to the earlier plastic chassis (and thus dropped some weight), I'd stop looking at compacts.
My advice at this point to anyone looking for compacts is to first decide how you want to use them (are they just for the occasional walk, and you'll use your bigger binoculars most of the time, or will these be heavily used -- for me it was the latter), and then try a good rev. porro or two against a couple of good roofs and decide which kind of image you prefer. If you must have the smallest binocular with the best image, the Zeiss Victory, Leica Ultravid and Swaro Pocket all had good images and were surprisingly bright for 20mm bins. The Zeiss and Leica seemed a bit better built to me, as the Swaro's focus and hinge seemed a bit fiddly, but my impressions were based on testing demos in stores with optical charts, not on extended periods used in the field.

Although, frankly, I don't think I'll get a pair. The more compact roofs I try, the more I realize just how good my 18 yr. old Venturer II reverse porros are. I like the 8x Vortex Hurricanes, but they have the issues you expect with a compact roof (touchy eye position, flare, etc... but I got 'em for $60, so I'm not complaining...) Still, I'll keep them (the reviews here may have been a bit harsh).
I think the Nikons, Hurricanes and my ZRS HDs probably cover it. I've also got some no-name Chinese 10x25s that are surprisingly good (poor QC, though- I tried out probably 10 pairs before I found the good ones....)
