i ordered mine as soon as i got home after seeing that email come in on my iPhone. can't wait to replace the proclip mount i've got up now that i used with my crappy treo 680 with the one for the iPhone!
I am definitely going to use the proclip vehicle mount, but I am on the fence regarding the device mount. I wish proclip made an 'active' mount like dension with a connector built into the bottom. I may try using the dension holder on the proclip mount. But i'm sure as hell not paying $200 bucks for the whole dension system, even if I could get it into this country and get tech support etc. I'll just have to figure out a way to patch the dension connector into my head unit my own way.
I ordered the ProClip with the adjustible holder and it works great. I have a shieldzone cover on it and it fits just fine, but I can adjust it larger should I decide to carry the phone in a case. I hope this helps!
