The iPad is a slick device that's capable of, well, just about anything you want it to do. It can even play back high-definition content from iTunes, which would be a lot more exciting if it had a high-definition screen. At 1024x768 it falls short.
One of the most exciting developments for fans of 3D is the upcoming 24/7 3D channel - a joint venture between Sony, Discovery and IMAX. In addition to bringing existing content to 3D, new shows are being created, specifically for 3D enjoyment.
If you're a fan of BBC programming like 'Doctor Who,' 'Top Gear,' or the reinvention of 'Sherlock Holmes,' then you'll be happy to know that BBC programming will finally be available in the US. You won't have to wait for BBC America to pick it up either.
You can't be blamed for sticking with 2D until the whole 3D thing starts to even out. The technology is still new and if you've got a great TV or projector, it makes sense that you'd want to stick with the gear you already love. There's a chance that you'll miss out on new content though, if it's produced only for 3D televisions.
