Whats the best wireless NAS device for windows network?

I REALLY like everything about the Apple Time Capsule other than I cannot find any hard evidence that it works well with the Pc (namely Vista). I think the HP Home MediaSmart Servers sound good as well but its not wireless in the same manner as the Time Capsule (I suppose I could hook it up via my wireless network, dunno) I have looked at the Drobo’s just a tad. Basically I want something I can connect to wireless but is located and secured at home. It will be used for basic backup, music and photos etc., storage. Anyone in the Fluther community have any experience or suggestions? Thanks in advance!!
