Honestly I'd be perfectly happy even without wifi on a reader (have never missed it on my Sony 350s), but since the Kobo Glo has it, I figured I might as well set it up and make use of it. I always have between 200-300 unread books on my reader, so it's not like I'd ever be in a situation of not having something to read.
And as already said, SugarSync works flawlessly with the Kobo.
Still, it would be nice if everything worked for all readers so we wouldn't need multiple cloud storage sites.
