I totally want one of those tough cases from case mate !
tried this one advertised here
Tuff-Luv Armour shell for Google Nexus One | Buy iPod and MP3 Accessories
case seems ok - not as tough as the case mate one - but it simply does not fit, both sides from the case do not meet each other pretty much all the way around, also the power switch is partially covered, guess the Nexus one is definately NOT the exact same shape as the HTC desire so dont be fooled by tight fitting cases for both phones, they wont work
damn! just waiting to hear back from tuff luv (i-nique) to see what they say...
