I wouldn't say necessary, but I've seen it touted as allowing instantaneous, split-second locating abilities. Used in addition to GPS, I think that GLONASS could really help with finding a satellite signal, particularly indoors in areas where GPS signal may be weak/poor.

GLONASS would be an excellent addition - but I can live without it.
As for the topic in this thread, that Nokia blog post definitely answers the question and confirms 64 GB - and that's awesome!! What sucks is that I purchased a 32 GB during that Amazon one-day sale a couple weeks back - I thought that was the max! Grrr. Oh well, we'll see how far it gets me. I doubt I'll be filling up 32 GB very fast, but I'm happy to know that 64 GB is supported!!
