I have downloaded fedora 10 final 4 days before the final release date. Generally speaking, it is very stable and faster than fedora 9. I tried the ext4 filesystem. It is up to 70% faster than ext3 and enumerating files are lightning fast. The new intel driver gives faster intel GMA 900 performance(about 30% in glxgears, previous 597 fps, now about 799fps).
Ok enough speaking, let's see the screenshots! Plymouth is cool. But I cannot take screenshot in the booting sequence.
