My submariner originally designed in the 1950s has a 42 hour power reserve, no winding no cables just a very nice watch that always works.
Any quartz watch would give you about 2 years, and even a modern winding watch would give you longer run time.
I am a linux/firewall admin, i have tried to use an iPad for this but its just a pain.
What it is good for, and i mean really good is as stated in posts before.. media.
I use it for watching youtube, checking/. and playing silly games and it is very good
I have searched an article like this for admins but there is none because
its a pain to use it for anything else than browsing or watching videos.
What has not yet been lifted in this thread is that OSX and IOS

and more aspects of the mac being locked in.
I am seriously looking at going back to Debian for my desktop.
