Things get changed either for better or worse, so if your device works as you need and want, then you should think twice before you upgrade.
OS 5.0 offers a better browser.
New features, like controlling which email address are included in the messages folder.
Setting custom alerts for individual contacts
there are really a lot of other features.
You can always upgrade and downgrade if you do not like the new OS.
