"... In the post "Nikon D3 and D300," we reported about the Nikon D3 that "the new 3-inch LCD has almost a megapixel of resolution." This was the result of a somewhat disingenuous if not deliberately misleading specification by Nikon, but it turns out it's not true. As LCDs are usually specified, the D3's LCD has 307,000 pixels of resolution."

Wrong I am afraid.
Check the DPreview hands on report of the D300 for more details.
Both nikon (900.000) and canon (230.000) use dots while they should be using pixels. Either way, the Nikon does indeed have 4 more dots (or 4 more pixels if you prefer), than the 40D.
Besides, the positioning of the dots of the D300 is also better which should result in a user experience even better than the 4 times pixels data suggest.
The 40D is an excellent camera, no doubt, but the screen of the D300 is simply in a totally different league. This will probably only be relevant for those users interested in the live view function. It appears that Nikon has once more tried to deliver a coherent sets of specification in order to deliver real world usefulness (live view + decent screen + AF ability) as opposed to a simple marketing gimmick.
