Thanks for the info so far!
With regards to the points addressed by Alfie, I'll explain a bit more as there's some crossed wires I think:
1) Hero is sluggish? How do you know yet?
All the previews and videos I've seen so far have indicated it's been great, and with more RAM than the Magic it should be faster if anything. The Galaxy looks as good (as the Magic), and Sony's won't be out for a long time anyway yet I imagine.
2) & 3) Custom ROMs are all well and good, but I'd prefer these things added by the operator, which as you say may happen with the next revision.
4) Haha, I can afford a card - I was more getting at the fact other phones have more built-in as standard (e.g. the Galaxy).
5) The battery stuff is just based on what I've read here and on Voda's forum, but one of the reasons I asked this here now is because the owners in this thread will have had a fair bit of time now and can provide a good bit of feedback
7) It is an "issue" with Vodafone, because that's who I am with and it's also who currently has the Magic exclusively - but as MarcLister says above, perhaps their exclusivity period may end soon, which also throws another spanner in the works in terms of me getting one soon, availability on other networks will undoubtedly lead to better deals!
