I have to say I haven't found myself using the HUD very much. When I am learning an app I usually want to have discoverability so I will search the menus looking for the stuff I need. Once I am more versed in using it I just memorize the keyboard shortcuts. Not to mention that for some apps (mainly Java etc) HUD doesn't really work at all.

Not seeing much in the software centre either.

HUD is perfect for the power users, adds a lot to productivity.

All of this stuff is faster with keyboard shortcuts, unless it's stuff that you only use very occasionally in which case there would be only a negligible benefit.

The algorithm is also based only on text matching (presumably levenshtein distance) so typing "exit" isn't helpful if the application happens to use the word "quit".

HUD would be incredible if it was as clever as Siri at NLP and could search every app installed on my system at once.

So I could say stuff like "Set an alarm for 10 minutes time" or "email richard"

> One feature I wished to have - a seamless OS upgrade like iOS.

What's wrong with the current OS upgrade process?

It has seams for a lot of people.

Personally, every upgrade I've done has resulted in a broken system. I'm not doing anything out of the ordinary. Half the time I'm left with a system that won't even boot and I have to do a fresh install.

Wow, that's odd. My desktop has been running the same installation since 10.04 or so and all the upgrades worked fine (apart from minor gnome-shell toolbar breakage).

I've had Ubuntu upgrades go pretty smoothly so far.

I would like it if you could run an upgrade process to switch to a 64bit install though. It seems at the moment as if a reinstall is required (or major hacking).

If you've initially installed a 32-bit OS and you expect a seamless upgrade to a 64-bit OS then it's honestly a use case that shouldn't be looked at or have resources devoted to solving.

You might be right but I'm not the only person that wants to do it.

A few years ago the recommendation (on the Ubuntu site) was to install the 32bit version but now the stability and performance gains of 64bit builds make the trade off different.

The box doubles as my home MythTV box (with uptime requirements to keep my family happy) and general home server including running as a test server.
