Couple of comments...
1) "bits" for routers are more properly referred to as cutters, I believe.2) in the Must Have section, I'd put a locking switch (essential if you have any plan to mount the router in a table). I'd say it ought to be capable of being operated whilst both your hands are holding the tool.
3) in the collet size section it ought to be mentioned that the largest size cutters are not available for 1/4" or 6mm routers, and perhaps that 1/4" and 1/2" have the largest range of cutters available compared to 6/8mm.4) More than most other power tools I'd be inclined to include a safety section - accidents involving routers are not uncommon with woodworkers, and they probably represent a much less obvious danger than tools such as circular saws. Accidents can happen extremely quickly, often a result of the cutter (rotating at anything up to 30,000rpm) grabbing the workpiece, or feeding stock into a table mounted router the wrong way. I'd say that resperatory protection is a must.
5) finally, what are the alternatives to a router? I'm hoping that Jacob is reading this, because he's challenged the "gotta have a router" position in the past, and it might be quite informative to see what common router tasks can be achieved with hand-tools. If the reader only needs the router for one of these tasks then they might decide that the router is not an essential item for them.
