There is lots of talk about an ATV (or other similar unit) that produces a great internet TV device. Putting all the content issues aside, there is one weak link that may affect many potential owners...ISP data limits. Many ISP firms now have monthly data limits based on plan. Cheaper plans have smaller limits. But more and more seem to be going this direction. Locally Cox has about 4 plans ranging from 100GB to 400 GB (around 45$ to 99$). Those with HDTV Smart TVs today may find its quite easy to chew up 10GB or more a day with modest watching. Add a family and a couple of sets going, and it could be larger still. Seems like this could be a real issue for any firm with a Internet based TV device. Maybe compression or something else would step in, but seems like a bit of a stumbling block... Thoughts?
