I haven't considered these too carefully, but let's see how we go
-Best Console (or PC)?For me, it's been all about PC, but that's more to do with my time/home situation than a lack of interest in the 360/PS3's libraries. I suppose XBLA has been my favourite "console" - if you'd have told me years ago that I'd be playing enhanced ports of NiGHTS/Virtua Fighter 2/Soul Calibur/Radiant Silvergun/Samurai Spirits 2/Guardian Heroes, etc. all on one mainstream modern service (and in the UK too!) I'd have called BS, but it obviously turned out to be true!
-Best Handheld?PSP. Between the DS and the PSP, the latter just has more of what I like on it. I think it was also a nice wake up call when it launched and sort-of proved that handheld gaming doesn't have to be the technology leper of the gaming world.
-Best Game Developer? Pfft, no clue.
-Best Innovation?Microtransactions? *is shot*
-Top 10 Games?The Last Remnant (PC)
FFF: Chocobo's Dungeon (Wii/DS)
Gu Jian Qi Tan 1 (& 2) (PC)
Phantasy Star Online 2 (PC)
Monster Hunter Freedom Unite (PSP)
Boku no Natsuyasumi 4 (PSP)
<insert more games here>
Edit:
a) I should stress the "microtransactions" suggestion was a (bad) joke
b) Stick Everybody's Golf 5 (PS3) on that games list

Editedit:
Add Mushihimesama Futari and Fortune Summoners to the list, as well as the entire Kiseki series

(is that ten?)
