The first google hit for TABLET 4G LTE is http://news.cnet.com/8301-1035_3-57485151-94/rim-finally-unveils-4g-lte-tablet-with-aug-9-launch/ and it seems to meet all your requirements, especially if you live in Canada.
Ideally what I would like is an iPod Touch with 4G, but that doesn't exist. I don't want a phone... I use a Verizon pre-paid cell which meets my needs, and I don't want to be saddled with an $80-$90 monthly bill. What I'd like is something with many of the features of a smart phone, but without the phone part. Does something like that exist?
I have looked at the Verizon Jetpack and other mi-fi type devices, and I may go that route, but that,s just one more piece of equipment to carry around. Also I don't want an iPad or any other tablet that large... The smaller the better.
So, what recommendations do you have for me?
