OS - PC
Browser - IE version 7.0.5730.11CO (yes, I'm behind on updating it) once in a while I remember that I have FireFox, too
USA
Card Captor Sakura, Fushigi Yugi, Mon Colle Knights, Weiss Kreuz, Yu-Gi-Oh! and so forth
Hmmm, not sure how 'boy band' they are, but currently listening avidly to the Eric Stuart Band (hey, he's the voice actor for Brock and James in Pokemon, and Seto Kaiba in YGO so there's even a legitimate anime connection! --
http://www.myspace.com/ericstuart ) Alan Parsons Project, Moody Blues, Queen (showing my age with these choices I'm sure)
I do have more than 100 items in my gallery, and collect non-anime art, too.
Not sure if this is a legitimate weird OS/browser combo, but I've looked at my gallery on my PSP to show cels to friends when I'm at work (no none work browsing permitted) -- it needs lots of sidescrolling. It would be cool if there were a version of RS that might display better on hand-held devices.
