I think that the OS4 screens we are seeing from Hyperion are acceptable, for now. Sure its no MacOSX, but who cares. As long as the usability is there, the UI is secondary.
I'm sure the guys at Hyperion will have plenty of time to do alot of UI manipulation and changing before the next couple of revisions ship. (v4.1, 4.2)
Until then, lets just pat the Hyperion team on the back for doing the impossible : Bringing back our beloved OS to the forefront. An achievement in itself.
We should look at this, as an intermediatory measure. This is our windows 95/98 people. We have been out of a major revision to AmigaOS for years, you can't expect Amiga to rival MacOSX or XP from the word go now do you? The kind of UI and functionality you guys want is something requiring a whole API system overhaul. Lets give them v4.2 and 4.5 before we cry blue murder. Besides by the time that happens, we'll all be too excited with the prospects of AmigaOS5, being on the same level as Windows Longhorn. Which is touted for an early 2006 release. Longhorn, will boast a full 3D accelerated UI, as will OS5 by that time.
From then on, Amiga will find itself on a more level playing field. Lets just hope Amiga's in for keeps this time round!
