I don't use Unity as a daily driver but I switched it off due to the network latency and general slowness inside a VM. Aside from that I thought it was pretty decent, it'd be nice if there was more content sources but you can't win them all.
BTW, you seem to have the name/numbers convention backwards :) it's codename during dev, numbers once released. So it's 12.10 or RR now.
Yes, much better. Working off a USB stick with persistent space, (I have the Gnome Ubuntu Remix as PC os at present) and this box has Nvidia graphics, and we have problems with the broadband. So as slow a combination as I can imagine anyone new to Ubuntu seeing.
Searches now seem to be completing before sending to Amazon, and my maths related file name terms were bringing up sensible UK relevant suggestions from Amazon, mainly textbook titles. This 'feature' has got a lot smoother since I first saw it.
I'm not entirely convinced that this is going to make a lot of money for Canonical. It will be interesting to see figures in a couple of releases if Canonical (which is a private company) decide to tell us.
What do we think the value to Amazon is of my random desktop searches for files & stuff on my desktop?
The 'slow typing' problem is real: search is dynamic and can, as a result of network latency and fat fingering show results of unfortunately shortened search terms. There is no content filtering on the results. That is actually why I switched it off.
