Well it's ok but iCloud has a 5gb limit And you can purchase more. For me 5gb is not enough but I like the whole iCloud idea and it will be very handy, but if you backup to iCloud then iTunes will not backup when you sync to the computer and I don't like that I rather back up to my comp and use all the free space I like but if you use all the space for music that's a lot of mp3s you can fit on there
I totally agree with you 5 gb is definitely not enough for me and I'm pretty sure 5 gb won't be enough for most people. I mean the only ipod that apple sells right now smaller than 5 gb is the ipod shuffle at 2gb. The nano comes in 8gb and 16 gb, which kinda tells you that users need and use more than 5 gb. I also don't think people will want to be forced to choose which music they will want to have with them all the time in the cloud, they would much rather just have their whole music library with them at all times. What do you think?
