How's the battery life? The FUD (?) around that is pretty much the only thing keeping me from jailbreaking.

Haven't really had it installed long enough here to notice, but my percentage hasn't gone down any more than it would normally in 3 hours or so. When using it previously on my 3G it had little to no effect on battery life, the phone itself was just slow. (I didn't jailbreak my 3G until after the iOS 4.0 update turned it to treacle)

Looking at the list of things he installed, I see absolutely no reason why any of it should affect battery performance. The problem is that once you give someone the power to do anything they want, some of the things the want to do are things that have consequences they don't want, and many people aren't good at correlating the benefits to the costs, even when it "seems obvious". As an example: if you install something that lets you have an animated HTML5 wallpaper, you are going to have some changes to your battery life. You may also see changes to general performance if the wallpaper doesn't deactivate while you are using apps. However: that's very specific to that extension. If you install something that changes what happens when a text message comes in, then (barring bugs in the implementation) it is only going to happen when a text message comes in, which is likely negligible. To the extent to which it is not negligible, then it should be a direct cost of the feature: if you want incoming text messages to be converted to a 3D ray-traced animation of Tom Hanks reading them aloud and uploaded to your Twitter account, that's going to take more power than, say, playing a different sound if the message contains the word "epic".

Huh? No offense but just jailbreaking your phone and then using it the same as always is going to have ZERO effect on your phone. If you use it with weird apps or have an animated homescreen background, yeah, you're going to see a battery hit. Just like if you install an app that streams music over 3g all day (regardless of whether or not you've jailbroken).

  No offense taken. I think it should be pretty clear that by "jailbreaking" I'm also referring to installing and using non-App store apps (what's the point otherwise?). I'm particularly concerned with the affect of running many apps that are using undocumented/unsanctioned apis (such as with the app that updates the weather icon). iOS has a bunch of restrictions to prevent apps from astonishingly degrading performance of the system (e.g. the API discourages or prevents apps from running invisibly in the background)
