Well it seems that the loss of USB Notes synchronisation functionality in iTunes at 10.8.1 was deliberate:
Contacts are now synchronising via iTunes again as of 10.8.2 and iOS 6 formal release but not Notes. You must now use either iCloud or an IMAP email account that Telstra (biggest Australian telco) does not offer.
Apple will get dissaffected customers if they start to withdraw functionality that was working on your model of iDevice. They also need to develop better sensitivity to their travelling customers being stung via data usage. Give users adequate control & iDevice cache data if possible – think Facetime optimisation, Maps update, iCloud Sync etc.
I am reluctant to embrace iCloud as I periodically travel overseas and Global Roaming can send you broke as matters stand. I can not just turn off roaming or cellular data as I still want to get SMS and updates to passbook for boarding passes & tickets.
Also Notes on an iDevice may have confidentiality or intellectual property sensitivity; do you want them on a public server? I notice too that Photo Stream is getting advertising – again increasing data usage – so what comes next with iCloud cost-wise?
We need an international treaty so that global roaming can no more than double your bill per service – split 50-50 home-away. Perhaps Apple could facilitate some such arrangement before the masses of new users loose confidence in smart devices?
