a beautiful UI is needed only for the technologically challenged...

for people who want to get work done (most of us here), what actually matters is the applications that matter. i.e. functional browser, fully capable office software, productivity tools, a robust core, strong media consumption softwares, etc....

the reason why debian, or any other distribution is a no-go for 90% of users, is because the openoffice or libreoffice cannot even handle a fully featured .docx properly......

People dont use a OS for marveling at an UI saying "my precious" whole day... some people got things to do.... (the whole reason, why people still stick to Windows)
