Finally, I have transferred my main working laptop, Acer Aspire 6930, to Fedora 11. Fedora 11 is much faster than Fedora 10, mate, and I find it really amazing.
Fedora 10 to 11 on Acer Aspire 6930 Update with Preupgrade
Fedora 10 to 11 on Dell D820 Update with Preupgrade
Everything went on flawless. The upgrade even updated Nvidia drivers from Livna.
