The upload is a big limitation for me right now with cloud Backups, with a 6mb upload I have to be very selective as to what I backup otherwise it'll not finish in the night and leave me with unusable Internet the next day.
Is that 6MByte/s or MBit/s? one of the reasons I've supplemented the FTTC with a 4G sim is that it gets ~30+Mbit/s upload which is useful for syncing stuff - we only get 5-6MBit/s upload here on the FTTC never mind the ~19MBit/s on the 80/20 product at our old house.
