I was lucky enough to be able to reserve and collect and iPhone 6 Plus 64Gb last Sunday from my local Apple store. Since then I've been using iOS 8.0 as that's what the phone came with. Is it worth updating to 8.1, or shall I wait until they've ironed out any issues with that version? 8.0 seems to be working well for me and I don't want to update if I might find issues, but understand that there may be some bug fixes that I may benefit from (although I haven't experienced any yet). Just after a general consensus on the experiences of others out there. TIA.
