The funny thing about resolution is that it scales with distance. If you can't see the pixels, then there is no difference between 800x480 and 10000000x50000000.
Oh and SLCD is IPS. The panel thats in my HTC Desire is the same tech that Apple uses. The only visible difference (other than aspect ratio) is that with my Desire I have to hold the phone 2" from my face before I see the pixels. With the iPhone 4 that number is 0.5".
Given that I typically hold my phone at 1' from my face there is literally NO DIFFERENCE between my Desire and the iPhone 4. I've done numerous comparisons to verify this. I'm also shortsighted, and my short range vision is very acute. For the average consumer there probably wouldn't be any difference at all.
Basically what that means is that your iPhone is doing extra work for nothing. For 3.7" phones the default resolution will probably always be 800x480. We'll probably see 1024x600 for 4"+ screens though, and with the larger screen size it will actually be worth it.
The one exception to this however is AMOLED. It has a 33% lower pixel count, and interpolates pixels to fake it's resolution, so 800x480 isn't even close to being enough, especially for 4" screens. To get the same visual quality enjoyed by the iPhone 4/Desire, the 4" SAMOLED phones made by Samsung would have to use 1280x800 screens.

I agree 100%, but thats AMOLED. A SLCD phone like the Desire/G2/Desire HD won't look like that. AMOLED in it's current form is garbage.
