1. (1GB [not Gb] RAM) Since this is a much requested feature and we finally found a way and components to do it, you can consider the probability that we will get 1GB RAM at around 95%. Doing a preorder will greatly improve the probability since the RAM is easier to source in 1000 quantities and we could do this when phase-V completed.

2. The difference in price between the bare GTA04-NeoN board to DIY-retrofit into your N900 and a complete Neo900 incl case and stuff from N900 will be around 150EUR at least. Of course you can make excellent use of a broken N900 with defect USB like this. And each single donation makes the device less expensive - again see rationale given in phase-V

3. Some guys already ported sailfishOS/Nemo to N950 and N9 and I have no doubt somebody will do same porting as soon as they get their hands onto a Neo900 with sufficient RAM. Particularly now that Neo900 will even support multitouch for pinch/rotate-gestures

You could consider the 100EUR donation like a season ticket to watch and contribute and participate (and of course support and make happen) one of the most exciting and entertaining projects of the last few years, and odds are in the end you even get your value back in form of a great device you can order discounted by 106 or 110 EUR. Your arguments to not do it seem to vanish like snow in the sun

Thanks for your interest and support
cheers
