Out at the lake with the wife, 2 kids, and parents. I decide to take the kids out for a flight to visit some friends. Around supper time, the wife & parents fire up the SPOT page to see where we are and they see a "last PIN" being about an hour earlier with nothing after that. You can imagine what they were thinking.
All the while we are fine and off to visit someone else at another lake before heading home before it getting dark. After getting home, I got right blasted by both wife and parents. About an hour later, the missing pins showed up on the spot page. Not sure what was going on, but it taught me that I should use my phone a bit more and be a bit more explicit about what my plans are going to be and when I expect to be home.
I love my SPOT, but it isn't 100% all of the time. It's only one of the tools that can/should be used when buzzing around out in the back country.

Andy,
No machine made by man is 100% reliable. Your SPOT flight-followers need to understand that and not expect that lack of a fresh reported position means you're in trouble.
In my experience SPOT works great maybe 95-98% of the time ... but my wife has learned that that's not 100%. Not that she doesn't worry when the signal is late from time to time, but she's also not calling SAR or giving me hell when I check in later.
The most frequent cause of a lack of SPOT tracking for me has been me - I sometimes forget to turn on the tracking feature!
Cell phones are much less reliable than SPOT ... VHF radio coverage is also less much reliable than SPOT - there's lots of large areas here in the mountainous, lightly populated west that at normal VFR single-engine non-turbocharged flight altitudes, you simply can't talk to ATC ... ditto on ATC radar coverage. Even sat phones and 406 mhz ELTs can still fail, just due to impact-related or electronic failures, battery drawdown, or inability to get out from under the tree canopy (should you suffer an accident in the deep woods), or you're in a deep, narrow canyon, or under water (gulp!).
When it comes to staying in touch while we're out and about in our airplanes, we have to depend upon a combination of layered communications (not to mention redundancies in our aircraft systems), good planning, good judgment, and a degree of luck, where no single machine or technology is expected to be 100%.
