I would say that MOS with new Peg boards is a given, but paying for major updates is just a natural progression. £50 (~$70) is a reasonable Western Europe/US price to pay for the features that people are assuming will come with 1.5, and the number of MOS users/potential MOS users who want them are not reflected here.

ATM the only thing missing for my needs is Papyrus office, but then I'm not the typical person out there looking for 'an alternative' which is where any more domestic sales will come from!

I think a 'donation' or pre-payment scheme is a bad idea, given whats happenned elsewhere. Trying to promote the Peg and get more sold is a more productive use of efforts (without ramming it down people's throats that is ) and alot of exposure can be created for very little money if we get creative ...
