Perhaps we sometimes expect too much. You don't listen to music to remember the lyrics, you just enjoy it. And you can enjoy and discard a piece of writing too.
You can easily idle away time. Right now I'm procrastinating.
I have used the keyboard navigation extension with Chrome, not sure if it's the same one.
The Chrome extension works well by default for a touch typist by setting the shortcuts to be available by typing two letter key codes, but you can change that from what I remember to numbers too.
Give Lynx and W3m a whirl they are both worth a look in. Lynx's numbered links mode is fantastic, to set it, you need to go to options>keypad mode.
The other browser, that makes link navigation a lot easier is Opera, use shift and arrows, to move around the links.
I love the above interface so much, it's so simple, and could easily be mimicked with a trackball and a touch pad such as that on the Blackberry. The Blackberry utilises a similar method for it's nav and menus and it's very easy, quick and intuitive to use.
Of course you could place the directions on the home row, for touch typists too. But I guess you can do something similar with Vimperator etc.
I read your blog post, and firsts thoughts were that shift and arrows could be used for OS UI navigation as well. Tiling window managers work well for me, but I have a lot of trouble with keyboard navigation in applications, mainly due to inconsistencies. Something as simple as moving from text pane, to toolbar, to sidebar - can require - some dexterous moves using function keys.
Hitting escape, and then moving around the UI with arrow keys would be much easier. Hit escape twice to move up the application stack. Hit the menu key - for context sensitive menu, hit escape->menu for app menu and so on.
Tabbed browsing for me is a real curse, as there is so much inconsistency between applications. This should be the preserve of window managers. So back to your blog post. Why haven't the best parts of some of the esoteric window managers propagated through to the mainstream OSs?
Interestingly tabbed browsing is what won me over to Opera and Firefox in the first place - the desktop OSs should have picked up on this earlier. It's a hack, to get around a poor desktop UI.
Back to Mozilla, why have they barely touched or been creative with the UI for the last decade? The native implementation of tabbed browsing is nothing but horrendous. I'm hoping some of this will be picked up with 'Pancake'!
I wouldn't agree that you can easily see a title in a tab! I'd rather a meta key that would bring up the info about the page easily - which listed the URI etc. But the title should remain at the forefront.
Just read the small blurb, and it doesn't really give much away. I do think Mozilla are right to challenge current paradigms, and I long for a bit of innovation.
The browser UI needs a chronic refresh, and thinking about what else the browser can do, is certainly worthy of consideration.
I personally would like to see the browser take on the challenge of navigation better.
I was confined to a 133MHZ text based machine for six months - and I happily learnt to navigate the web with Lynx - by using its keyboard shortcut-ted numbered links! It was amazing how easy it all felt, and it's something I've longed to see as an option in a browser ever since. This one thing alone would make using my Kindle's browser - bearable.
I recently considered ditching my cheapo freeview hard disk recorder (UK - Brand Digihome) and replacing it with a media box. I tried out a few distros and open source solutions, but they all had their faults in one way or another. I tried XBMC, Boxee, Myth etc on various distros on moderate hardware, and in the end - I decided it just wasn't worth the headache.
So I see a need for something that's easy as pie to use with abundant features. But why not improve and contribute to existing projects?
You mention that the Unity interface is poorly suited for 10ft interaction - you couldn't be more right. Am I the only one left in the world without a cinema display? Just watch the interface demo over at Ubuntu to see how much it sucks. It helps to be able to read type on the screen for tux sake. It's so amateurish.
That's not to say that your list isn't surmountable, and that there isn't a better interface out there yet to be untapped.
I can't read a white background unless I'm in a very bright room. Off whites are better for me. But personally I prefer light on dark. But it's a personal thing.
I rue the day the browser default background colour changed from being light grey to white.
