Over here in Tokyo, we can get an iPad from softbank on a credit agreement, so pay 24 monthly payments instead of the lump sum at the start. This makes the extra for 3G option just 500 yen more a month than the regular (Don't need to sign up for a data contract for this either!). So I am thinking if it is just a little more for the 3G, will it be worth it? what are the extra features of the 3G that are missing in the wifi? GPS? I don't care so much for the access now as i have hacked my iPhone to share it's 3G with my notebook and will do the same for the iPad. But I am just curious if I will kick myself down the road if I just get the wifi??? It could be useful if I am abroad to get a sim card and just put it in... Thoughts???
