I'd love to be the guy that keeps stuff till it breaks. Sadly i rarely keep stuff long enough for the warranty to expire.
i use to... but now were well trained by the tech companies with the newer! faster! shiny! must buy one! approach.
First laptop died. Can't say i've had anything break since. Sorry to hear about your news MRU! The rest has been upgrades/changes for the sake of it. I'm trying to break the cycle tho.
Apart from some early laptops, these being single core laptops (i only started in 07 but have made up for it) nothing i've had has gotten slow. Ok i bought an iPhone 4S at the start of the year before i got a 6+. The 4S was already slow but not too bad.
It's how you look after them but even that for any device doesn't guarantee it to last.
iPad? I use to charge once a week! Owned iPad 2/mini/retina mini/Air. 64bit should outlast the old for speed and keeping the updates coming for longer.
Owned Nexus 7 2012/13 none of the issues i read about.
Owned Mac Pro Classic/Air/2014 Pro. No issues at all. No staingate, crashes etc. Zero problems.
Android handsets. Too many to list but no issues and all sold on.
iPhone 3GS, 4, 4S, 5 and 6+. No problems.
I wont list the pre smartphones but again... no problems.
All apart from signature gone in working order. Luck? Or looking after them?
