I disagree there, thinking back to the days of when Office 'customized' it's UI to how you used the product (constantly moving menu items, shudder!), I'd rather have a consistent UX that didn't exactly fit my patterns than an adaptive one.
The problem with many interfaces, especially on consumer products, is that they're not discoverable, and oftentimes hide things behind inane levels of menu. Interface isn't a competitive advantage (although it should be!) so manufacturers don't invest in it.
I spend a good amount of time doing support. I still play around with plugins, tools, and interfaces, but I try really hard to stick with defaults. One thing I do often do is remap Caps Lock to CTRL and it surprised me how often this catches people (and drives me nuts when I'm using their computer).
I have a Logitech Harmony 700 (a very mainstream universal remote), I don't care for it but it's the best I could find, because I use a receiver and Apple TV. Whenever I have guests it's always a mystery for them how to use it.
