Standard def video will look awful on the new iPad
I was going to upgrade to the new iPad but when I looked at my main use cases for the current iPad 2 it includes a massive amount of video watching. These videos are mostly standard definition or streams from other sources all of which are in standard definition. This is due to my slow broadband speed where I live.
Taking this into consideration, the new iPad would show the same videos but I imagine they would look blocky and pixelated which would mean the upgrade would actually be a downgrade for me.
I also use Sling quite a lot and their track record of slow updates is another big turn off. Just something to keep in mind if you do use your iPad in a similar way too me.
