I am not exactly an early acquirer, and I tend to hang on to technology long past its average life. Witness my old iPhone 2 (still working fine), my iPad (a first generation device that I bought on closeout when the iPad 2 came out, and I'm still enchanted) and, until now, my GPS. I have had one of those old fat Garmin GPS devices that looked like a miniature CRT. The batteries died years ago (only worked when plugged in), the power cable was getting a little wonky, the touchscreen would occasionally and intermittently get out of registration, and the maps and software had never been updated (last time I checked, a few years back, it was $99 or something and it seemed better to buy a new box)
It owed me nothing - not exactly sure when I purchased it, probably 2006 - it went with me (via checked luggage) all over the USA on business trips. Occasionally, I'd pull up the history and find directions to a hospital 2000 miles away, to the southwest. It was, all in all, a VERY USEFUL and RELIABLE bit of technology.
The last few months, I have found myself relying on my iPhone maps app for directions (and more importantly, traffic) so I knew it was time to update.
Picked up a Garmin Nuvi 40LS (hey, I'm still not an early acquirer and I'm cheap!) that came with a lifetime map / software update for $120, on sale at Staples. I'ev never liked the Tom Tom User Interface, so Garmin it is again, even 10 years later the Garmin GUI is familiar. A real impulse buy (I went in looking for a low profile extension cord, came out with a notebook, pens, and a GPS.)
