Matus, just one thought here on film vs. digital. (I prefer film in general, for my photography.)
I too have been traveling alot for work lately, to Asia and the USA mostly. I got tired of carrying film with me, asking it to be hand inspected instead of X-rayed (not always possible). My trips often involved short multiple stops in several cities, so many airport security checks, etc. Plus I often carry more film with me than I use (because I don't have time to shop for film in the cities i visit), so some film gets brought alot on more than one trip. I also like ASA 1600 films...
In the end I got tired abotu worrying about X-Ray fogging, and bought a Panasonic LX-5 AND a Canon S90. I am going to sell one of them, but I haven't decided which yet. So far, I see quite similar image quality between the two.
I use the S90 MUCH more because it is sooo small. The 24mm vs. 28mm equiv. zoom doesn't matter so much to me, as I'm not a very wide-angle kinda guy.
The Lx-5 clearly wins with regards to multiformat (1:1, 3:4, 2:3, 16:9). It's nice for me, because I like 1:1. I much prefer the user interface on the Canon compared to the Panasonic, but this can be a matter of taste.
Enjoy whichever camera, film or digital, you decide to go for!
