Impatient as I am I looked around the Adobe ftp server to see if Adobe Reader X is available yet. It is: Look under Code: ftp://ftp.adobe.com/pub/adobe/reader/mac/10.x/ for the Mac OS X version, and under Code: ftp://ftp.adobe.com/pub/adobe/reader/win/10.x/ for the Windows version. Or just wait for it to hit the website. Screenshots: Installer: Yes, it uses a bit much space for a PDF reader... Dock icon: User interface: Native UI elements? Who uses native UI elements? Not Adobe.
