Some of this is very true. Going from GB to ICS isn't that bad with your data backups however steping down is another headache all together.( I just recently transfered all my apps and data to the ELTEVO and everything went smooth. Restoring apps and data in batches is ok but titanium paid also lets you freeze and defrost, uninstall apps, backup to the cloud, set schedules, get a full overview of your app storage use, wipe dalvic, change system apps to user apps and vice versa. Its probably the second best investment on your android. (first being the android itself)
