Hi all, first post here

A little bit of background: I like Finland pretty much and would love to move there; I'm sharpening my professional skills to, with any luck, eventually land a job that let me go live there.
About the subject of this post:
Since I recently switched jobs I will have to wait until next year to get my vacations so I have plenty of time ahead to save money and plan a nice trip. Because I will be able to spend only a maximum of twenty days there I would like to know about your suggestions about the places / stuff-to-do I definitely shouldn't miss once there.
So far this is the list of the cities I would like to visit - in the order I plan to do it:
- Tampere: I have to visit Tampere. Also it's the hometown of Noora Louhimo, singer of Battle Beast; there's no way I can avoid it.
- Rauma: because it's a bucolic place
- Uusikaupunki: beautiful place with a rich history and heritage, can't miss it
- Tuurku: a beautiful place and cultural hub, can't miss it.
- Espoo: here's where this motherf*cker I know lives so I naturally have to stop by to drink some beers and vodka and spend a couple of days there. Also he told me that Espoo is transitioning to a technology city (like Silicon Valley) where renowned companies and start-ups alike are settling every day so I agree it's a must for me to visit the place (by the way, I'm Unix-like sysadmin).
- Helsinki: though expensive as hell I need to stay there a minimum of 3 days. There's a lot of stuff to see and I specially don't want to miss the chance to visit the Aalto University as well the F-Secure and Jolla HQs.
Thoughts? I know there are a lot of places to visit, every and each one is more beautiful than its neighbor but my time - and money - is quite finite, not to mention the air tickets themselves

Cheers,
-Martin
