I've just published a very thorough comparison of iPhone's Safari to all the current Windows Mobile web browsers - and Opera Mini running on all mobile platforms (except for, unfortunately, iPhone). See http://www.smartphonemag.com/cms/blog/9/full-roundup-browsing-web-windows-mobile-just-iphone-incl-iem6-review
I've seen it crash once on 2.2. Really, just once...it was a huge page with loads of images so I'm not completely surprised. It actually loaded once, but crashed when I went back and reloaded at one point. --Eric
Because the reason some people avoiding 2.2 is their iPhones are jailbroken and they have so many mod-apps that might mess up the system, eg: BossPrefs. These people have no right of blaming Safari the way they have no right of blaming TS Tennis for not running properly on their jailbroken iPhones. If jailbreak isn't his reason, then he'd better upgrade to 2.2. He has nothing to lose.
If you don't want to update, don't complain about the performance. Safari on the iPhone is MUCH better at displaying pages than Windows Mobile browsers. It is the ONLY complete mobile browser at the moment. My only issue with it is that a large animated gif can still cause it to crash. Everything else seems to have been resolved.
What is it with people demanding that there should be a flash player...I for one am happy nytimes.com and other sites aren't bogged down with flash ads and "OH MY GOSH! NO WAY!" sound effects from idiotic banners. Safari, as it stands now is the most advanced, user friendly, and well developed mobile browsing app going, because of it's simplicity. And I totally agree with the other posters regarding the lack of sympathy for 2.1 jailbreakers.
You're lucky Nevertheless, the crashes aren't that big an issue IMHO - I still prefer Web browsing on my iPhone because Safari is just faster and easier to use than anything on Windows Mobile.
I have never had any problems with Safari, it works very well and I doubt the Microsoft Mobile works very well at all considering their current rate of failure.
I'm really happy that Apple does not ship Flash for Safari. I wanna kill someone every time Flash starts to play a YouTube-high-quality-movie with the great framerate of 3 frames per second on 100% CPU on my iMac G5 (which handels every other movie format up to 720p without problems). And guess who is to blame when my account is slow and the cpu is used to 95%? Yeah, of course, it's flash in the Safari of my gfs account eating up everything to display (tadah!) a scrolling banner with news from a tv station in a skyscraper ad. So keep this garbage off my phone until it's fully optimized, which obviously will never happen (prove above). And, btw: Can you name one single browser on a mobile device, which offers Flash? The real Flash, not the mobile edition of it. I can't. Must have some cause.
