Do not know about you but being a old Unix and now Linux guy .... I can any 10.6 Mac or newer and be able to do my work.... And they just work. I might need to get make a few things ... But I can work. Iphone fits into this Eco system out of the box as well. Tried a Google phone htc Samsung and iOcean and some other cheaper android phones .... Hardware wise none have survived. Fun to cook roms etc ... But I worked in IT for about 30 years. Now I just want to turn it on.
Now going back to hardware life span. Jesus I have first gen PowerBook still working a bondi blue iMac still working... G4 Frankenstein still working ... At work we have about 150 Mac minis running as image servers still plugging away... Did install Linux on them .... Never really saw issues with Mac hardware. Of course stuff breaks... But Apple care was always a great service. Biggest problem was always hard drives.
Now about the watch ... Interesting applications being developed... But meh
I use the aquasana and is great for coffee and tea.... Also a special China prefilter comes with kitchen counter one I have. Used the same one in beijing for many years. Filters last about 6 monthes and pre filters bi monthly. In beijing the prefilters lasted about 4 monthes.
Ok not to sound like an ass ... People still want MS certs? I have only been in the web side of things for a long time .... Even given windows laptops as a option no one takes them.... Last company I was at in Beijing before early retirement had one Windows machine out of 300 company laptops and on server side not a single windows box. In Canada we had again out of 700 company laptops 3 windows machines used by QA .... And 1 in accounting ... No windows servers out of 800 virtual servers. In China is their still demand?
