3G Access Only for iPad? I am considering recommending an iPad for an older relative that currently has no computer and no Internet access. I get reasonable 3G reception from this person's home. Internet access options start at roughly $60/month. So, I am considering recommending a 3G iPad and using only the 3G service for Internet access.  

Obviously this would be slower than a high speed Wi-Fi connection, but it would also be much cheaper and I think it might be adequate. I am wondering if anyone has experience with using 3G as the primary internet connection source.
I use my iPad all day at work for email, web browsing, etc. on 3G and it works fine without Wi-Fi for everyday use.

From a speed perspective, don't sweat it.  For a user who obviously doesn't sound accustomed to blazing broadband, I think 3G will be just fine. Internet is fast enough, Netflix works, and YouTube and the like are fast enough (although YouTube seems to limit the quality of the streams, but it's good enough).

EDIT: The original version of this answer highlighted why an iPad would not function properly without a computer, which is not true since the release of iOS 5.
