Forward the Penguin Army!
(Yes, i know 'droid is not a try Linux distro (yet))
Recently I have had two suffer two upgrades. The first to Ubuntu 10.04 (yeah, I know it's not 'droid) and the second to Windows 7.
Did Lucid annoy and frustrate me? Yeah, a bit. But I'm used to it now, even the window buttons (although I move those if the mood took me). It does everything I need, I can mount .ISOs natively, get to what I want in a few clicks, run Flash and have a full-power CLI if I need it.
Windows7 on the other hand...oh dear god...what a horror. The new Explorer is simply terrible (although I quite like the new address bar that I have got used to it) but almost everything else is inconsistent/horrible. The Admin challenge is, frankly, infantile and pointless as it does not ask for a password. Actions are constantly blocked for no reason (trying to copy from the network to C:\? Good luck!). Actions that should be challenged, aren't (e.g. hacking around with Environment Variables). Flash fails to run. Too much real estate is lost to the task bar and windows borders. Why the FECK do IE tabs appear as separate items on the task bar? Two clicks to get to the current tab? WTF? At least FF behaves itself. Getting to deeper system options is tortuous. It is, frankly, the worst version of Windows since ME I have ever had to encounter (I avoided Vista).
My advice? Stick with XP until 2014 and then go to a Linux distro (maybe "Ylmf"). *DO NOT* inflict Win7 on your end users.
