plinth

Hey, I think I'm going to get a Magic soon (on Vodafone in the UK) and I've seen a lot of talk about rooting, roms, cupcake and even running the Hero sense ui on the Magic.

I'd like to know what are the main benefits to tweaking/changing/upgrading the Magic's OS, or if I should just stick to what comes out of the box.

I know Vodafone tend to brand their handsets heavily, which I don't like, and would prefer the Magic to be as Google/HTC intended it - would rooting/a ROM change this? (I've flashed & debranded my old K800 in the past which improved it no end)

Thanks
