Hi. I have got two Macs with BlueTooth built in and I love it, especially text messaging through Address Book. Anyway my girlfreind also has two Macs (do Apple give commission?) but without BlueTooth. She has recently got a BlueTooth phone and needs a dongle. I have seen this one: D-Link DBT-120. From what I have seen it looks the best. It will be to sync with a Sony S700i which have a few issues with Mac. Will this add anymore problems using a dongle. With a bit of playing around the S700i syncs fine with my two computers.
