I'm sure there are 3.5 people out there who will put Sony's portable Blu-ray player to great use. It has a 9-inch screen, 4.5 hours of battery life, and 1080p output via HDMI. But for the rest of us, The Sony SX910 is an extremely niche-y, borderline unnecessary piece of tech.
99.9999999999999% of us would be better served with a tablet and a Netflix account, because Blu-ray's 1080p resolution is basically wasted on a screen so small. But I sort of get it. Hypothetically there is a Blu-ray enthusiast out there who also spends a lot of time on the road, and really doesn't want to waste their time obtaining digital or DVD copies of movies they already own.
The Portable Blu-ray player will be available this Spring. [Sony]
