well it seems like nod32 is written in assembly. anything in assembly seems to be guaranteed gold. Just hope they keep developing and include rootkit removal and better user friendliness( last i heard they had rootkit detection on demand but nothing for removal). I haven't tried it yet but I love the idea of smaller programs.
Looking at the opera browser executable file, ITS ONLY 77.5 KB. you guys should try loading up IE7, lastest mozilla firefox and opera. you'll notice that opera > IE7> Firefox.
same thing sorta goes hand in hand with av. I think some reviews show that nod32 scans really fast (er than norton) but even then doesn't scan every file like the other anti viruses. (config issue?)
