Just wanted to post that I'm using Vista Ultimate 64-bit (OEM) and I have two NSLU2 units with V2.3RA5 firmware and have no issues at all with the units under the new OS. I had read there were SAMBA compatibility problems with the earlier versions of Vista and required the user to change some settings. I did not have to change any settings to get the NSLU2 to work. Just right clicked Computer and mapped the drives. I'm getting around 5.9MB per second from either of the units. Folder response time seems much more 'snappier' than it did using Windows XP. May be some sort of caching feature designed for mapped network drives. Overall, I'm thoroughly impressed with Vista. I have run into a few bugs ( for example, standby doesn't work properly on my system ), but I'm sure issues like these will get ironed out. I think the most impressive thing was the fact that 'The Neverhood' even works under Vista. HOLY CRAP! The bestest game eva!
