IPhone – Are the iPhone 4 charger and iPod 4 charger different

• If you're using Windows, you're basically locked into using iTunes to manage your content; some people don't like iTunes.
• Syncing non-media content is weird, too. There isn't a unified sync system. I sync calendar via Google Calendar, notes via SimpleNote, and general files with Dropbox. Some apps only sync with your computer over WiFi, which is a hassle for me at work where the wireless network is not set to permit this. Sync is really important for the iPod Touch because it's nice to have a lot of your data at hand all the time, but it's a pain to type it in manually because it's so small.
• You can't easily update podcasts on the device. I couldn't sync for one week one time and had to update each episode by finding it in the iTunes store.
• It's really smooth, so if your hands are greasy it's easy to drop. Mine has handled drops well. I'm glad I use plastic screen protectors, though.

These are the most potent drawbacks I could come up with. I haven't found any comparable devices that solve these problems any better, though. Non-phone smart devices that fit in your pocket that aren't iPod Touches basically don't exist now; there are some Android devices in the works. I'm delighted by my iPod Touch and absolutely recommend the device.

The older USB cables from iPod days have deeper and thicker plastic enclosures on the 30 pin end as well as physical buttons on the sides to help disengage the metal "ratchets".

The connectors that came with the iPhones had much weaker springs for the side "ratchets" so you could just pull to detach the connector.

Here is a Bluetooth iPhone charger (that is slightly larger and thicker than the iPod model) with a current iPhone cable for comparison.

The cables are all functionally equivalent once seated so you don't need to worry about current or power since even the oldest USB cable can carry all the signals needed for the latest iOS products and chargers.
