In reply to climb the peak:
Personally I don't think it's worth paying the extra money.
Touring bikes give you:
More relaxed geometry - comfortable all day
Stronger - for load carrying
Braze-ons for panniers
Kudos - among other tourers
You can get all of the above with either a cyclocross bike or an old steel mountain bike. (a Specialized Hard Rock Sport circa 1995 will get you more points among cyclo-tourists than any of your Surlys)
What kind of bike you need depends a bit on what kind of touring you plan to do
- all tarmac or some tracks?
- travelling light or heavily loaded? (4 major components to this (1) how long are you going for? (2) what do you expect the weather to be like? (3) where will you be sleeping - hostels / campsites / wild? and (4) are you cooking for yourself or eating out?)
- How remote will you be? The further from civilisation (and a bike shop) the sturdier (and simpler) the bike you'll need.
I use a Specialised Tricross which is very good for touring.
ps - if you're on a budget go second hand. Especially valid for touring bikes which are built like tanks and go on for years.
