Hey I can understand one would like that service, but the price at which they are providing it is really high! As a swiss citizen, I'd never subscribe :s
I wouldn't subscribe whilst in Switzerland either, but I'am considering using their service while traveling. Since I only have to actually open about 2-3 Mails per month, I think the price is ok. At least a don't know anybody who would (and I trust to) handle my mails for ~36 CHF per month except my parents. But I feel kind of bad using them as my "secretaries".
