Great! We now have tablets that have 100+GB of Storage, my question is who really cares? There are really three camps when it comes to computers, the mobile ( aka tablets ), The portable ( aka laptops / ultrabooks ) and Desktop Computing. Who wants to blur the lines?
People who can't afford, don't have space for or just do not want a tablet AND a laptop AND a desktop. Many people who are perfectly happy with just a tablet and a laptop - a desktop would be better in certain cases but not enough for them to buy one as well. Some of them so rarely touch the laptop (perceived as old and slow) now that most stuff gets done on the tablet because of the convenience even if its far from the best tool for the job.
Only a fool enforces rapid password changes and complex passwords.
Or someone who has to follow rules like PCI DSS which requires you to change passwords at least every 90 days, be at least 7 char long, include numeric and alphabetic char, not be the same as any of the previous 4 passwords, auto lockout after 6 attempts for at least 30 minutes etc. Don't like that rule and the card companies don't want you handling card payments which makes business a bit hard.
Personally I'd prefer the option of teaching people to use a decent password and not change/share it but we do not have that option. As it is its a constant battle* with users forgetting their new password, using someone elses, writing it down so they remember it etc. Rapid complex password changes are viewed by many users as a problem which they try to workarround in order to get their job done.
* A battle we have pretty much won but needs constant vigilance to keep it that way which makes the IT people the bad guys.
