Here are some real facts and hope it will help ya
Some Good Features of both phones
K800/K790:
-is better at night pictures because of xenon flash
-has A2dp meaning you can use wireless stereo headset to listen to your music
-faster UI and navigating through menu and different applications
N73:
-Better Video recording
-Symbian OS, it is a smartphone, able to install and run more applications than k800/k790
-Loud 3d speakers

-Quad-Band, EDGE, 3G
some Bad points of both phones
K790/K800
-not a smartphone
-video recording is useless
-memory stick micro m2 only 1 gig at the moment
-lens cover
-not a Quad-Band
-k800 has 3g but no EDGE, K790 has edge but no 3g
N73
- No A2DP
- slower UI than K800/K790
- built quality is ok but squeaks
Summary
Both are fantastic phones, i say it is a draw and both are targeted into different buyers
K790/K800 - someone who likes to use it as a cellphone to call someone and that likes good camera, mp3 player and a few decent applications
N73 - someone who likes to run lots of applications( excel,PDF,tomtomGPS,word,powerpoint, etc..) and use it more than a cellphone, likes taking pictures and recording video clips and listening through loud 3d speakers, better reception
I say the K800 wins on Night Pictures and faster UI navigation
but N73 wins overall because of its smartphone capability and higher external memory capacity at the moment
