That's one reason, yes.
But regardless, so far I haven't been able to control capacitive screens at an accuracy of less than 3 or 4 millimeters, even with a stylus.
Plus, I can control a resistive screen with the tip of my fingernail. It isn't as accurate as a stylus, but still a lot more than my fingertip.

That's true, but it's just a matter of habit, not a real problem. I for one am sometimes slightly irritated when using a capacitive screen (mostly when trying to use my fingernail). Think of it as the difference between using a (good) fountain pen and a (good) ballpoint pen! It's noticeable, but not a problem if you're used to it.
I've often heard questions like yours from people who only know bad resistive screens, like you'll often find in public terminals (need a lot of pressure, usually poorly calibrated, often scratched). I too prefer a capacitive screen over those any time. But a good resistive screen is a totally different story.


@Kabouik:
My requirements are as follows (roughly sorted by priority):
1. fits in my pocket
2. has a hardware keyboard
3. runs a FLOSS operating system/doesn't come with a proprietary license
4. can make and receive phone calls and SMS
5. allows basic web browsing

The N900 does 1 and 4 very well. 2 is acceptable. 3 and 5 become increasingly difficult due to the age.
The Neo900 would improve in 3 and 5, although not by much I guess. All the other points are pretty much unchanged.
The Pyra would certainly be an improvement in 5, probably in 2 and 3. 1 and 4 would suffer, but I hope to an acceptable amount.
The GPD Win would clearly improve 5 the most, probably improve 2, but fail miserably in all other points.
