2.0 was a media campaign that really didn't mean much, all they really did was renumber the channels to group them into categories as THEY saw fit. Now, all the sports channels (sans HD) are in the 500s, news & info in 400s, etc. Did they make any major changes to technology? In a word, NO!
The quality of their DVRs (which you MUST have one per HDTV) suck. I have had one unit replaced 5 times in 7 months. Also, if you are happy with what Insight offers NOW, you are all set, but do NOT look for them to add much in the way of HD any time soon.
BTW, to get the HD to function properly here, it only took Insight about 6 trips over a 3 month period to get the picture not to pixelate as badly, artifact not as often, etc.
I had D* several years ago, left them for E* for local channels, and then to Insight for HD. Of the 3, Insight is the worst, IMO. Now waiting to see if D* makes good on promises (ads) to add lots of HD content as they now offer nothing special and E*'s HD is a joke, from what I see of it (PQ sux on HD) and channels are "interesting" (Mom always said to say that rather than saying are downright chitty.) Seriously, the Voom channels are worthless to me as I don't want to watch the same old BAD (as in they were not good when they were made long ago) movies over and over and over. (Yes, there IS a reason that Voom went under!)
Am not sure that you will be happy with the (lack of) tech support, service (if needed), etc. from Insight, the programming or quality of their hardware. You may very well wish to do what I am doing, wait and see if D* makes good on their promises (the satellites are either in place or will soon be there for the HD channels) and take a look at them.
The biggest UPSIDE to Insight is there are no contracts to sign or term commitments, so you can bail out on them at will.
Good luck!
