Every time I think about smartwatches, I just think about how much I miss Pebble. I loved my Steel and Time Steel, and was bummed that the company failed before the Time Steel 2 happened.
I wonder if it would be possible to recreate something like this for real, with cartridges for each software/tool (like a gameboy or similar?), excluding the comically tiny keyboard probably :P
Today $300 or less can buy a watch that runs UNIX, can emulate any machine in 1981 in realtime, and stream data from the ARPAInternet over a wireless connection orders of magnitude faster than any leased line.
Sounds like a €30 smartwatch I've seen some 7 years ago. Yep, it costed that back then. It ran Android 4.4 and even the battery was user replaceable.
I think it was called QW09.
Unfortunately, I was 10 at the time, and €30 sounded like a lot to me, so I didn't buy it :(
