Ok, after several hours of uage, here is my initial first impression.
1) Look nice, and seem solidly build.
2) The texture of the N1's back, is about similar to my GPS, Garmin Nuvi 755T.
3) Aha, I got the engraved N1. It is a real engrave and it is not a paint coat.
4) I got Celcom 3G (voice+data plan), and with proper APN setting I got a 3G connection.
5) Connection wise, in my house@Balakong, seem to be similar what my Nokia E52. Yeah, I can get good 3G coverage, but, sometime it down to E or GPRS.Actually similar to my E52 and my wife's SE K770i. I'll try again if I going out later.
6) Yeah, the signal bar dropped 1 bar if I hold it.
7) The firmware/software version IS SAME AS the shahz's.
8) Since this is my first SMARTPHONE, I have to get used to it first

...
9) My first apps is... the 'Terminal Emulator'
10) I changed the scaling_governor for cpufreq from the ondemant to
conservative. This make the N1 to set the cpu speed lean towards to much lower speed. I hope I can save a bit more of power.
11) Yeah it is 'warm' when, I do intensive browsing and settings.
12) I charged my N1 with my Nokia E52's charger

... Yes, it warm during the charging. It is warm, NOT the hot sizzling hot.. The warmess is about similar as my RAZR V3xx and E52.
13) Yeah, the 'hard buttons' on the bottom is not responsive as other places in the middle of the screen. BUT, I still use it comfortably as I get used to it.
14) N1 is running cool with USB charging. So the heat source is most probably from the high currnet (1A) battery charging from wall charger. IMHO... this is normal.
Ok, I already test the audio SQ very very briefly....
1) With my custom IEMs, UM Mages, the sound is ... flat, with no bump at any frequency spectrum,
2) To my ears, the bass and treble extension is not as wide as other high quality audio devices. BUT, still listenable
3) The audio ouput is just OK, and not as loud as my E52 and Sony Walkman X1000. This is might be the reason the sound is not as dynamic and extended as my Sony Walkman x1000.
I'll update this later.
As a person who just get to know Android and smartphone. My intial verdict :
NICE. Actually it is about the same feeling when I use my friend's iPhone 3Gs.
As a hardcore GNU/Linux user : EXCELLENT!!!, excellent computing platform.
Ok... going back to
Market 
Thanks to shahz, irwan, ... that make this possible.
Thank you
I added my N1's HOME screenshot
