First, i will say thank you to all the guys here in the forum which assisted me solving my problems.
And second, i will thank all the developers, which have done and are doing a very well work !
Hardware i use : MSI K8N Neo Platinum, AMD 3400+ ( newcastle ), 1 GB Corsair Ram, 160 GB Sata, LG CD/DVD Multiformat Burner, MSI Nvidia 9600SE Graphic Card, Hauppauge PVR 350
And now my thoughts / experience
I decided to switch my mixed environment based on RH 9 with W2k running in a VMware box to a pure FCx_64 system. After a few tries with FC2_64 now on FC3_64. Everything works well and stable. But doing a closer look, there are some sort of problems i was unable to solve. In my opinion, FC3_64 works well on the server side, i.e. Apache, Samba, Postfix with Cyrus and so on. Yum's redesign looks very good for me. But on the other hand there are so much things not really working, that i feel, FC3_64 is far away from a typical desktop system. So why ? Due to it's lack of Hardware support ? NO ! The Hardwaresupport is great. It lacks a lot of things that i want to use on my private desktop. This starts with the install of firefox 32 bit ( in 64bit no language support , no flash, ... ), same to thunderbird. Next, fairly poor support of multimedia, all the things that make live more funny, like tv recording via the PVR, play DVD's, MP3's. For me the desktop story of FC3_64 ended running in a lot of troubles using my samba server ( running on FC1 ), where after updating my new FC3 system i am unable to write to the shares - but oops, same user can do from any other systems ( RH9, Debian stable). So now, i will give it up at the moment and switch back to the roots.
From my point of view FC3_64 as a desktop is rock solid for business applications, both desktop and server, but, as i mentioned before, far away from a "everyone's" private desktop system. Hopefully, FC4/5/6/... will solve this.
Last, a list of all the things which did not work for me (means, the big rest works fine ! )
VMware Workstation ( 4.5.2 ) - worked under FC2 ( i need this for GPS apps )
buggy samba client
AMD 64 PowerNow glitchy
TV viewing / recording
PS : excuse my english, i have done my best
