I would like to do a clean install and format the hard drive, rather than upgrade from Vista on my HTPC. My biggest challenge will be iTunes and the phone. I think it will mostly go smooth, but thought I would ask just in case. - Apps. I don't have all apps on my phone. Some are on the computer. Since these will get wiped, can I/should I first find their location and copy them to a seperate partition, then added back in the iTunes folder after the Win7 install? - Backups. I have 2 phones. I suppose if I sync both first, I will have all the data I need. I will lose my iphone backups, but after the reinstall of iTunes, I suppose it will automatically create new backups? - Playlists. I heard that smart playlists are broken in 3.1+ (or something like this). Should I somehow try to migrate the playlists since they may not be properly contained on the phone? - Computer Authorization. I don't know if its a big deal, but I guess I will need to reauthorize the computer, which will lose one of the authorizations. - Other. Anything else to consider? Other than this, since it is a HTPC it should be pretty easy. I only have a handful of programs installed on it and all of the media is in a seperate partition. Any time I do a full wipe of the OS, it always makes me a little nervous I will miss something.
