These "not bad" changes in Windows 8 also underscore a recurring problem with software: people are forced to choose between "take the good and the bad" or "nothing", they can't just take the "good". Software updates are too big and bundled when the reality is that a lot of components could sensibly be upgraded by themselves.
Changes in Task Manager for instance could have been folded into any version of Windows to date, and if a few programmers had access to the right source code I'm sure they could have added this at least to XP. Yet they can't, and Microsoft won't, and users of any version other than 8 are kept from a perfectly sensible improvement.
Rather than charging $200 for an "upgrade", sometimes I think it would make a lot more sense if you could pay Microsoft $10 for the "new system utilities package" (which would update your Windows XP Task Manager alone, and whatever else falls into that category). In other words, don't restrict access to the truly useful upgrades just because no one wants Metro.
