I am currently owning a D90. I know that it has a crop factor of 1.5. Does it mean that I will never be able to get a wide angle lens, knowing that a lens of 18mm focal length would be 27mm instead?

no... nikon has the 12-24mm. sigma has the 10-24mm & tokina 12-24. all are specifically designed for DX format cameras.

for digital,

four thirds, we have 7-14mm (14-28 35mm equiv) the 2nd widest FOV I can find now.

1st will be Sigma 12-24mm on FF body.

then, I'm curious as a beginner, comparing if no plan going for FX cam, getting a wide angle FX lens or DX lens, which is better worth?

iirc, the widest FF shd be the AF 14mm?

anyway, DX users are not short of options when it comes to WA lenses, regardless the brand.
In the case of Nikkor lenses, am I only limited to DX lenses? Because a 50mm AF-D F1.4 would be 75mm and it isn't exactly a normal lens at that point of time. And what is WA?

Read your manual to see which lenses can be used. Also, check Nikon website.
