An easy and good (the best) way of keeping afloat, while searching for new land to settle...
That depends on your business model and future plans, I don't pretend to know what deals Hyperion are planning for the future. They seem pretty "afloat" right now so no worries from me. Either way, you've got MOS and if your happy with that, well, more power to you I guess. Enjoy it, and if OS4 dies you still have MOS. Either way the Amiga scene has plenty of NG choice right now, X1000, SAM, MOS or AROS, the choice is yours. Just don't go deluding yourself that any of them will be competition for Microsoft, it ain't going to happen.
