I presently have a Hero (HTC Hero EU, 1.5 unlocked, on Vodafone UK) and I'm quite tempted to get an HTC Desire (2.1 unlocked), which will hopefully be available in about a week. What's the situation with going from one device to another? I will be transferring my MicroSD card so my data (pretty much just photos) will be on the new device but my settings and apps won't be, as I understand it. As I will be using the same Google account, will all my market purchases be there ready to download for free? Will app specific settings be lost (e.g. high-scores, preferences) or are they typically on the SD card? Basically I'm concerned about running into something nasty that I hadn't considered so I'm wondering if there are any gotchas I should know about.
