In reply to buzby:
Lots of points made by lots of dSLR advocates and it looks like the UKC consensus is to go dSLR, so if you're going by a straw poll, why not ? It's probably worth considering (and although it sounds kinda trite) that whatever camera you've got with you will be the one that takes you the best pix and it'll be the one you'll learn quickest from too if it's got useful components like a wide lens (for landscapes) with a big aperture (for isolating objects in the field depth), a viewfinder (for composition), full manual controls (over exposure time, aperture and ISO), an ND filter (for longer exposure times in daylight) etc.
Here's my thoughts on pros/cons and it'd be interesting to know if any of the dSLR advocates agree/disagree with them.
A dSLR's strength is that it has some extra focus tracking technology that allows it to shoot more frames in sharp focus faster, and in lower light than other types of digital cameras, although in respect of landscape photography, not so much of a benefit perhaps ? Its weakness for climbing/hiking/skiing etc is that it is bigger and heavier, and while some obviously see its larger size and heavier weight as giving a handling advantage, it just depends if you mind lugging it about. A dSLR from Canon or Nikon will also give you a big choice of quality modern lenses ... if you can afford them.
A compact's strength is that it fits in your pocket and having an integrated and versatile all-in-one lens also means you can't change its lens. Despite what some might have you believe, its viewfinder can be very good indeed. However it has a smaller sensor than a mirrorless or dSLR so the pix you take will have less latitude for cropping or tweaking if you don't get them absolutely right.
A mirrorless camera's strength is that it can do everything a dSLR can wrt lens interchangeability and is smaller/lighter than a dSLR and has a short lens to sensor flange distance that can be used to mount all sorts of weird and wonderful adapted lenses. That means you can access the whole of ebay's 1950's to 1990's lens stock and buy a lens that may have cost a month's wages back in the day for £25 or so, but you'll have to manually focus, manually control aperture etc. Modern lens choices are more limited though and even the best won't let you take action shots as reliably as a dSLR will with a modern AF lens.
