Bluefoot, are you by chance based in Helsinki or Tampere area in Finland? My problem with your posts (and why I don't answer them as often) is that you often get a lot of things right but also horribly wrong many times - and explaining all those facets can be quite time-consuming for me, that I'd rather spend with my family in the evening instead of explaining. I don't think you get things wrong from point of view of analysis - you seem quite capable in that area, but that you don't have all the data needed to do a full analysis and have a full understanding. Consider this post a voucher for a few free beverages with me if I'm in same town as you at some point and let's talk about mobile business in general. EDIT: And if you're way too far out of the way for this ever being a likelihood, come talk to me on IRC, irc.freenode.net, nickname "Stskeeps"
