New Features and Enhancements on the iPad 3
Internet connections speeds should be comparable between the two models. Both the iPad 2 and iPad 3 have Bluetooth capabilities and Wi-Fi capable of accessing all major 802.11 b/g/n networks. Basically, this means that if you have a Wireless Internet connection available, your iPad can access it. The iPad 3 has also increased the cellular network speed from 3G to 4G for models that have Wireless-G installed. iPad 3 also comes equipped with support for iCloud services. iCloud services enable the user to keep all files, mail, notes and contacts synced across multiple computers. So, if you are working on a iWork document, it will automatically save and be immediately accesible through any Macintosh device with iCloud support.
One important change comes in the form of additional battery life. The iPad 2 had a 25 hour battery, while the iPad three has almost doubled that at 42.5 hours.
