750 Euros deposit on a Dev mobo? Why didn't they just get the 100 Dev mobos and then advertise them to OS4 Devs and beta testers and skip the deposit? Or is the required deposit more of a trial balloon to see what future sales are going to look like? I do like the bit no one will be considered a end user if they are chosen. Will that mean EU consumer laws do not apply? I'll take a guess that will mean that the consumer release, those buying these Dev mobos will have to pay for that OS release.
