Those who don't remember history are doomed to repeat it
1960s: Mainframe. Access the applications from anywhere! So long as there's a bigass 3270 terminal on your desk and you can live with JCL. Score: 10/10 for badass virtualization trickery (still not bested). 2/10 for user experience.
1970s: Mini. Visual terminals allow you to access the applications from anywhere! So long as your sysadmin can find the uniquely weird RJ connector that your VT220 keyboard needs, and you dream in amber screen. Score: 10/10 for the lovely bouncy rubbery keyboard, 11/10 for indestructible fault tolerance in VMS, 1/10 for SHOUTY /VERBOSE USER:INTERFACE
1980s: Unix. What's in your /usr/bin? So long as the application is ed. Well, it is the standard text editor. And there's always Kermit for those home workers. Score: 9/10 for elegance. 1/10 for lovably insane hacks to get it to hang together (termcap I'm looking at you). 11/10 for the beards.
1990s: Sun. The Network Is the Computer! NIS, autofs, NFS. The golden age imho. Graphical applications from anywhere. You'll prise my X-terminal out of my cold, dead hands. We'll give some points to Sun for the SunRay...and immediately take them away for NIS+.
2000s: Windows. Roaming profiles baby! The less said about this the better. Oh, and netbooks, cos who needs full Windows right? And dynamic on-demand installation of parts of Office, to reduce the bloat. Because what is more joy for an IT manager than a thousand desktops where Office is broken in subtly different ways?
2010s: Chromebooks. Access the applications from anywhere! So long as you don't need anything fat like Office, and are the 0.001% of the population that have a web app that runs well offline, and use files that sync cleanly when you do reconnect and find that Pam in Marketing was working on the same file you were while you were out getting hipster massages. Score: TBD.
I love new tech, but this is a haaaarrrrrd problem.
