Woo! They must have been paying attention because they actually made each of the changes I'd requested in all of the reviews that I posted sans the LCD that listed the UTM coordinates.
I was one of the early adopters but unlike some of the people here I actually had good experiences with mine.
Having used the 1st gen device a fair amount, I've found that it doesn't impact my hiking much at all as it's pretty unubtrusive. At dinner, I pull it out and hit the button while I'm boiling water. Or, if I find a really cool spot that I want to come back to, I'll tag it with an OK.
It does however, impact my homelife quite a lot, is basically my way of saying that my family doesn't freak on my solo trips at all anymore. My parents would worry like crazy and my wife would nag me about my trips if they were more than an overnighter. Now after a couple years they know that I'll check in if I need and have the option of rescue – no nagging from any of them. I use the OK a lot, but I've only had to use the help feature when I had vehicle problems.
Thankfully, I was able to customize my help info to mention my AAA number and to call them if it locates my position as on a road, so my dad who lives in Missouri was able to call a towtruck to help me when I was up at a remote trailhead in Colorado (I just needed a jumpstart). Three hours after sending the message, my assistance arrived, so it worked pretty slick. I'd have had a long hike to the nearest house and even further to the nearest cell reception.
I'll have to figure out what their upgrade policies are, but I know I'll be looking to switch as soon as they hit the market.
Oh, price wise, for me the $100 = more hiking time, working out over the year, it's not too bad. My least favorite bit though is to get the tracking option, it's $50 / year extra so I've never used it. They do however have an excellent rescue insurance plan.
