In Canada your landlord is required to pay back your deposit with interest, so if you gave them a $1000 deposit and stayed for 10 years and interest is at 5% they would be giving you back about $1600.

Very few actually do this and most of the time interest is so low nobody bothers to fight for it.

How low-tech is still tech?

I want a device that can be armed and if moved without being disarmed (optional passcode) will set off an alarm.

This is both for my laptop when working in public spaces and for my cooler/food bag when camping.
