At first I did not think much of seeing the Apollo alpha version being released last week. I have followed the Apollo progress since early last year by keeping tabs at Adobe labs and attending or and viewing the great on-line presentations.
But it took a day or so for the light to go on that this was an alpha version and it was on the Adobe home page!
Adobe has plenty of new marketing initiatives in play such as Adobe Creative Suite 3. So it does not appear they are in need of some attention.
Thus the importance they are placing on Apollo appears very significant to holler about it on the home page.
The alpha supported operating systems are:
Windows XP with Service Pack 2 (SP2)
Vista Home premium edition
Mac OSX 10.4 on PPC or Intel
