I guess I'll just post up things here as I notice them, since I am not good at keeping long lists in my head.
Minor annoyance: In keeping with Microsoft's effort to turn computers into cell phones, all programs are now called "Apps". OK. Whatever.
Cool new thing: The list of all "Apps" (ie programs) in the start menu is alphabetized with letter headers at the beginning of each section. I find this easier as I can look for the first letter of the program I want instead of having to scroll through the annoyingly small font list that was provided in Windows 7 (not to mention that the list in W7 was also preceded by a very long list of stuff that appeared to be random. It included things that I had recently used but it also included stuff that I had never used).
Did I mention that Windows - X pulls up a list of Utility programs like Control Panel.
Also, the Notifications button in the icon section of the taskbar seems to have a pretty comprehensive list of stuff that you can quickly access.
Having fixed the one problem with the card reader, I am pleased so far.
So there you go.
