Is it my imagination of do these devices last longer with some people than other? I still have my first Sandisk Sansa MP3 player - still working in a slightly wonky way after being crushed and repaired at home with bits soldered on. The 2nd Sandisk still works perfectly and is over 3 years old. My ancient Nokia phone is now about 10 years old, we recharge it for use by overseas relatives when they visit Australia. Yet my lovely husband, a genius with anything mechanical, can reduce a phone or any electronic device to waste within about 12 months!
I'll bet my Kobo is still working in 5 years time. Oh, and I still have a working 1995 Cassiopaeia (but it didn't have rechargeable batteries).
