I'll take it back!

Just right after the copying files and restart, it instantly recognize my Intel WiFi 4965AGN wireless card, and ATI x1400 mobility and configures it all out by itself, and finishes the install.
After the setup finishes, i was required to update just 5 drivers, ( includes the manual installation on StigmaTel HD audio, and few other Dell Inspiron apps. )
After the final restart, it's humming beautiful, and I'm pretty happy to keep it until August ( or the first RTM release ), and considering very seriously on purchasing the retail Windows 7 license.

No more OEM fuckers.
Gentlemen, give Windows 7 a try! Just make sure you have USB flash drive contains the wireless and/or wired drivers from Vista ( NOT XP ) for W7, just in case it don't recognize the default network drivers that comes with W7. ( If you have Intel WiFi 4965AGN or older card, you are in instantly luck! )
