Not sure how many sports fans are out there, but if you haven't stumbled upon ESPN Motion yet (or are scared to install it), I'd give it a shot. Basically it is a background app that downloads videos in the background. I usually hit ESPN.com three or four times a day (once in the morning, once when Page2 is out, and once at night) and when I do they have a video (usually NBA tonight or perhaps top 10 plays of the day) ready to view. No streaming, not waiting, and pretty good quality too. Very smooth. No idea how it works on Macs or Linux, but it works great for me. Also cool is the new ESPN Intelligence page.
ESPN is throwing up ads after the video plays on the ESPN Motion, but it's either one of their cool "Without Sports" ads, or even better the super cool "23 vs 39" ad (Eric Neel's article on how they made it here). All they need to do is throw a SportCenter commercial or two on there and I'm set.
While I'm at it, even if you are the type of person who only watches sports during the final four and the super bowl, you should check out Bill Simmon's articles. Good times. Definitely check out the "Holy Trilogy of the Katate Kid" article.
My day has been wasted waiting for Prometric, a part of The Thomson Corporation, to get their freakin' application actually working (hey Prometric, you need computer training? Contact me!). Oh well, perhaps I'll feel better and maybe this is for the better. Probably not in my best interest to take a three hour exam hopped up on cold medicine.
