Over at Wired they have a great breakdown of the differences between the basic, Wi-Fi-only iPad model and the 3G model (which won't be out until later this April).
Which model will be best for you? It depends on your needs, including factors such as:
- Mobility (access to Wi-Fi at home vs. frequent travel)
- Storage (media eats up lots of gigs)
- The redundancy possibility for iPhone and iPod Touch owners
- No contract for 3G (awesome!)
Which model will you purchase (if any)?
