Short conclusion of the last hour: computers are all over the same... this one has just crashed and uuuuuuuuuuuuups away is my story. Sorry, you have to wait another couple of days.
I have arrived (again healthy and fine ;-)) in Oruro some hours ago and will continue to La Paz tomorrow (by bus - normal and flat alphalt roads are a little bit boring after what I have seen).
There I'll have several options... climbings mountains, visit the Lake of Titicaca... I'll keep you updated.
