There's a lot of other tweaks which make iOS a much nicer place. More recently, Nitrous is a pretty amazing tweak which enables the Nitro JS engine for non-Safari apps. Speeds things up big time. Aside from that you can have a way of having a particular browser open besides Safari, scrobble your iTunes tracks automatically, password protect apps, have a much better lockscreen experience, much better folder experience, theming, retina-fy low res apps, have a download manager, etc. For me personally, there's plenty of reasons to jailbreak.
