Upgrade Works!
10.04 is the first version of Ubuntu I've installed that could successfully upgrade my Dell laptops from the immediately prior version and remain useable when finished. Hooray! It even found my Inspiron 1545's Broadcom WiFi and successfully upgraded the driver for the first time ever. Nothing crashes so far, all apps seem operational and all data is intact.
It took them long enough, but now Ubuntu is almost as easy to upgrade as my Macs. Better ten years late than never I suppose.
Of course the key problem with Ubuntu remains, despite window controls on the left and much nicer default colour schemes and icons, etc., it isn't significantly *better* than the competition in any respect, it's just not much worse anymore. It used to be very Windows-like, now it's more Mac-like, but it isn't better than a Mac so why should anyone using a Mac (or Windows) switch?
It needs a quantum advance over the other systems, some totally new and revolutionary features that make using Ubuntu more fun and more pleasant, easier and more reliable, than other computers. That's the only way to get people to switch systems. It needs something revolutionary like multi-touch, iPhone OS and the Apple app store. But simply aping that would be too late now, they'd only be chasing Apple again instead of leading. That's open source's Achille's heel - design by committee doesn't produce innovation, only emulation of what's already been tried. Like MS they're too scared to knock over the table and switch to Boggle in the middle of a Monopoly game.
