A lot of what .mac offers you, you could setup with a simple Pentium PC and a Copy of FreeBSD/Linux, but heres where its got me:
I have a bluetooth mobile phone, it syncs with my mac every night, if I take my phone out and the battery is dead, simple I logon to the nearest pc and pull up my address book (which is sync'd to my mobile phone) so i have my sim card online! its fantastic!!
Mail is a little shabby for such an expensive item, but they should have a online calendar with mail and addressbook... that links to your ical
If im out and want to upload a file to my iDisk so i can pick it up at home, i can do.
Heres what apple REALLY need to improve to keep users paying:
* Up the mail storage to at least 500mb or 1gb,
* Give users 10 free mail accounts for the family, this can be shared across the 500mb or 1gb.
* Make iDisk work with windows, idea here is portability, if im at work i can upload to my idisk. hey saves money on those horrible little usb pen things
* Please upgrade your servers, they are painfully slow compared to other services when it comes to homepages.
my oppinion anyway, personally never used the free stuff in the idisk because it always hangs the finder.
