Well, I've had SP2 for XP running on my laptop for two days now and so far everything is smooth. The install detected Zone Alarm Pro, and so kept the Windows Firewall disabled. It also detected Norton as my Anti-Virus software, so no problems on either of those two fronts. I run Apache rather than IIS on XP, mainly because you are limited to a single web site with IIS on anything other than Servers. And once again, no problems here either. Apache is sitting contently serving up my .cfm pages so CF is working happily too. I'm beginning to wonder what all the fuss was about :) I've not really checked out the updated version of IE, simply because my primary browser is Firefox, but I will get around to it at some point. As for email/newsgroup, I use Thunderbird so any changes to Outlook Express will pass me by. So... were there any issues? Well, my wireless connection bombed after the initial restart, but I've put that down to things still configuring themselves as after I rebooted again, it's worked flawlessly. In fact, it's working better as previously my connection would drop about 5 mins into my initial browsing session. Possibly because I'm using WPA rather than the older WEP, and XP initially had problems with WPA, which were supposed to get sorted with SP2. The only other issue of significance I've noticed is that XP takes longer to boot. I recently rebuilt my laptop from scratch so I know the slowdown isn't because it's saturated with useless software. For now I can live with it, but I may consider a memory upgrade in the not so distant future (I was going to upgrade to 1GB anyway).
