One thing noticeable right off the bat is the new parental controls tab in the Preferences. You can now disable podcasts, explicit material, the music store, and shared content. 5.0 also offers calendar and contact synchronization if you are using Microsoft Outlook or Outlook Express.
Unfortunately, I don’t use either, so these last two things don’t help me a bit. As far as the music store goes, it still feels dog slow to me.
I saw Griffin Technology’s iTalk at Best Buy today. It allows you to record audio on your iPod. No, I didn’t pick one up.
The Times in Britain has an article entitled Apple bites back against music rivals with iPhone. According to this article, the new iPhones (at least from the British supplier) will only have capacity for 25 songs. An article in the Register also reports that songs for these devices will be $2 per song. They’ll have to up the capacity to something that compares to my current iPod for me to even consider something like this.
