RE: Curious question

Hi James,

Thanks for the codes, I will try them out.

Well, you ended saying that there is no need to
upgrade. But then I have to ask why do people upgrade
all the time?

In my case, moving from Windows 2000 to Windows XP, it
was because I found Windows XP handled wireless better
than Windows 2000 and I think alot of software seems
to be standardized for XP and not 2000.

Right now, Ubuntu seems to be taking off. But what
does Ubuntu offer me or anyone that another Distro
like SuSE or CentOS does not offer?
