Novell, RedHat and Sun Commit to a Linux Desktop
I am curious about Sun's motivation.
I think it's been obvious for years, now, that Sun's motivation is: toppling Microsoft while being competitive against IBM, HP, Dell, SGI, etc.
The Java Desktop System, plus the Java Enterprise System (aka Sun ONE), plus Solaris, plus Java is their portfolio to this end. You say only Java, but taken together Sun's product line is very formidable. For example, I'd still choose Solaris x86 on some servers without regretting it, and, then, using Linux where Linux-specific (read lazily programmed and non-portable) software is needed.
