$28/month. Same as I'm paying now. Yeah, it hurt the first month I paid it but it's worth it for all it does. If push came to shove, I'd give up the home wifi first and then just do everything on the phone with an occasional visit to Tully's to use their wifi if I needed to do things on the computer. This would mainly be for things like website and HTML newsletter design as those would be too tough on the small screen. Oh, and I can't use the "pay my bills" function at my credit union on the phone for some reason so that, too. From what I've played around with so far, I can do everything else on the phone just fine.

Luckily, I'm grandfathered into unlimited wifi so I don't have to monitor my usage. I've noticed they now have tiers but I haven't paid attention to what the new prices are so I don't know what you'll pay when you finally take the leap.
