There are a lot of reasons, but I’ll state just two.
1. When it was launched, it costed $200 more than the Nikon D40. And for what? For higher resolution? Not worth it. 
Especially if you care more about your DSLR’s flash shutter speed. D40x has a much slower maximum flash shutterspeed than the D40. Like what I always say to people who ask me, I’d save the $200 excess to buy a better lens. Or a better flash, perhaps. Why don’t you go over to Kenrockwell’s review site to save me time explaining? He wrote a pretty extensive review on D40x. Besides, you’ll probably believe an expert photographer more than you’ll believe me.
2. The Nikon D40x is rumored to be faced out soon, and will be replaced by a better, more powerful Nikon D60. I’d drool over the upcoming Nikon D60, but I think about the pros and cons, and the value of my money, and I’d still probably end up choosing the classic Nikon D80. But of course, if budget is a priority, Nikon D40, IMHO, is still the best investment you can get.
I say, get a Nikon D40 (I hear it costs about P22K nalang, if you’re gona buy it from Hidalgo, Quiapo — teh ultimate photography haven here in the Philippines), and spend the rest of your money buying better lens. Don’t be deceived by the “x”. The “x” in Nikon D40x does not mean more.
Hi Joni. Tara na, let’s buy your camera.

Nice review links about the Nikon cameras. I’m deciding on buying the D40 or the D60 in Hongkong this April but still, I haven’t decided which one to choose. I went to Hildalgo just last Friday and the d40 is about 21k with kitlens, and other freebies already with a tripod, bag etc. The D60 kit and freebies on the other hand is priced at 31k. I wonder which should I choose and whether the airflow control of the D60 is a worth upgrade.

1. A few months after you bought your D40, I got so excited and ended up buying a D40x after doing a week-long research and inquiries here and there.
2. After getting the D40x, I stumbled upon that Ken Rockwell site. (F$#k! that site!). It was so informative, a really great camera review site. He praises the D40 so much I started to hate my D40x.
3. Interestingly, one real advantage of the D40 is its higher flash sync compared to the D40x. This means you get slightly sharper images when using the flash in dark lightings.
4. The D40x sensor is the same sensor used for D80s. While the D40 sensor was really something new at the time Nikon launched it.
BOTTOMLINE: The Nikon D40 is the best entry-level DSLR out there. But if you have some extra cash to spare, go for the D60!!! There’s simply way too many advancements made on it.
