MacBook Pro, iPhone, and iPad Air here. Been thinking about going all Apple for online services. Am a current Gmail user, plus an institutional Exchange account, so that'd mean going to iCloud mail, for better or worse. Formerly used SugarSync to sync selected folders on my MBP to all devices. With SS no longer being free long-term -- which is fine -- and with me playing with the idea of going all Apple, I'm trying to figure out how to go all iCloud if I were so inclined. Basically, I'd like to be able to have all sorts of PDFs and other odds and ends available easily and quickly across all devices, including saving them originally on the iPad or iPhone, even if I get them as email attachments. Using iBooks for PDFs seems a little... suboptimal, and I'm unsure if relying on Pages / Numbers / Keynote iCloud syncing is the way to go for Office stuff. Anyone have any suggestions? TIA.
