I haven't entirely returned to the Amiga scene after leaving it in 2001-ish. I've got a few Amigas, but I'm waiting on some parts to repair/upgrade them before I dig in.
I've seen enough activity in the community/platform to spark a genuine interest again.
I'm sure there are more like me, and more that would return even if as a hobby as soon as it delivers on a few features like OS4 (For more than AmigaOne, or a moderately reasonably priced AmigaOne) and JAmiga/AmiZilla etc...
I'm not in a huge hurry, my 10 prior years as an Amiga user taught me that, so it's still fun to tinker with and see just how much of my computing I CAN do on the Miggy.
