Re: Should i use Gentoo?
I am using gentoo as well.
I installed gentoo almost 2 years ago because I could not get some apps in ubuntu (and other OS fedora, suse). If they were available I anded up in dependancy problems. The apps were hugin, autopano-sift, opera, epson printer driver.
After the well known learning curve I got them installed in gentoo. I recently checked the apps with Gutsy and they are ok now.
Reasons for gentoo are the speed (is clearly faster than ubuntu but the difference is not that big that is should be the only reason to switch to gentoo; the difference is less visible the more powerful your computer is); good documentation, recent software versions available.
Forums are excellent as well (small but specialized people actively responding)
