Just for completeness, I'm also running OpenOffice on the PC and the laptop, and Firefox. I love OpenOffice's PDF export, and gradually working my way around its quirks - particularly trying to print from Impress which sometimes choose to print the print border and not centre the slides - but getting there.
I've put Thunderbird on the laptop for email, but that's only for ad-hoc pickups. I'm still using Outllok as my main PIM on the PC.
