It would be nice to see some standardized testing done. If you don't have a standardized test, you'd have to test the tools over and over again. You can't have one test drilling 1/2 holes, the next drilling 5/8 holes, the next 3/4, the next 1/2 with different bits, the next 1", the next 5/8 in different wood, the next 1/2 in different wood, etc. The tests should be discussed before any testing is done because people might have some good ideas that might not be obvious, such as measuring the trueness of a cordless drill.
It'd also be nice to test things like the cordless rotary hammers to see if they're powerful enough to replace the corded versions. In fact, we should probably use corded tools not only in terms of seeing whether or not the cordless versions can keep up, but also as reference points since their longevity is superior. (You could even use a Kill-A-Watt meter to gauge how hard each different set of wood is. Not sure what level of precision those things have, but if they have 1/10th of a watt precision, that should be fine.)
I'd also like to see little gadgets that people have found and liked. I picked up this at Home Depot and was pleasantly surprised. First day I got it, I wanted to see how strong it was, so I drilled a 3/4" hole into wood. Much to my surprise, it worked perfectly fine. A little bit of the drill's strength was lost (maybe about 10%,) but that's still many times stronger (~450 in-lbs) than a true right angle drill (~150 in-lbs.)
