But when Microsoft change the GUI (as they did between 3.1 and 95, 2000 and XP, XP and Vista and will between Vista and Windows 8) so there is always going to be relearning as technology advances.
Shouldn't people have the choice which new GUI they learn?
And the relearning curve doesn't seem to be hindering the Mac, or the iPad, both of which face the same challenge and yet are taking market share.
Also, I think this is slowly becoming less of an issue. A substantial number (10-15% of global PC market share, depending who you ask) of users have made the jump to Mac, which is quite different from Windows. And on top of that, many now use iPads or Android tablets, with even newer UI paradigms.
When you combine this with much of your data now being available through cloud services, the barrier for trying something like Linux should become lower.
