Last night I was surfing around on the world wide web & found this:
Microsoft’s 4G LTE Surface 2 costs $679 and packs 64GB of storage. The Microsoft slate is significantly cheaper than the 64GB model of Apple’s LTE-enabled iPad Air, which sells for $829. Both devices are available without a contract, leaving you free to purchase however much data you need.

If you opt for the iPad, you can set your tablet up with AT&T, Sprint, Verizon or T-Mobile, the latter of which offers 200MB of free data per month. Sprint provides 1GB/3GB/6GB of data for $14.99/$34.99/$49.99 per month, while Verizon sells 1GB/2GB/6GB of monthly data for $20/$30/$50 per month.
