It's still not as widely available as we would like, but Nikon's D3S has finally moved from "this thing simply has to be vaporware" to "I may catch one in stock if I stay up all night clicking around." Without a doubt, it's one of the most impressive leaps in digital imaging at the $5k DSLR level that we've ever seen, and it has become next to essential when dealing with tragic lighting conditions on trade show floors. But as with every gem, there's a flaw or two be found somewhere. For those who plunked down thousands to bring home Nikon's low light monster, how would you change things if given the opportunity? Would you have bumped the movie mode to 1080p? Put a few more buttons on the rear? Lightened the load a bit? Go on and spill your guts below -- you've earned the chance, chief.
