And corporate users, who have a WinXP desktop with IE6.
I'm working on a customer site at the moment, where IE6 is the only permitted browser, the web proxy blocks sites which may install other browsers, so the only way to access many websites is to use my laptop with a 3G dongle to get direct access to the internet.
Somehow, although PortableApps' Firefox worked once (loaded by USB stick, as the website was barred), it, too, is now somehow blocked.
When browsing, I'm not too bothered about IE6's lack of compliance, but the lack of tabbed browsing means that it's impossible to organise a few sets of web pages together into a coherent set. (What *did* we do before tabbed browsing?!!)
