Levou 40 minutos para baixar e instalar tudo.
A melhoria mais visível foi no plasma:

1. plasmoid para twitter voltou a funcionar (mais agora uso choqok)
2. o calendario do relório digital está mais integrado com o korganizer
3. é possivel dar reload no feed rss
4. O knetstats parou de funcionar
5. O knetdockapp parou de funcionar
6. O knemo também não funcionou
7. E o plasma saio do ar algumas vezes.

Ainda bem que instalei em um HD de testes, pois para mim ainda não valeu a pena.
