I'm from the ZX81/Sinclair QL (remember those??) generation......
Yes, I worked on the QL ... if nothing else there's a bug fix in one of the chips which is down to me!
The press launch in the Intercontinental was good fun too. I wasn't in too good a state, whilst sitting on the platform pressing buttons for the TV cameras, having not really sobered up from the previous night before starting on the Buck's Fizz for breakfast. But I only missed one cue.
Win7 doesn't include Outlook Express, neither is it compatible with it. A silly thing for Microsoft to have done as the supposed replacement, 'Windows Live Mail' is truly awful.
Thunderbird is only slightly different in most everyday uses to OE, and will import OE message bases. There are some minor UI irritations (things that are harder to do than with OE for no obviously good reason) but nothing serious that I've come across.
