Should I buy a Lenovo for editing 4K video?

Episode 1277

Steve from Hermosa Beach, CA
Lenovo ThinkPad P50

Steve is planning to buy a new laptop and is looking at the Lenovo P50 because it allows him to use dual PCI drives built in, plus a third SSD for data. Leo says that makes it a bit heavy at 6 pounds and is mostly a desktop replacement. Steve says it's worth it because he's editing 4K video. Leo says it can certainly do that because it has a Xenon processor, up to 64GB of memory and supports Thunderbolt and USB Type C. It's a nice rig. What's remarkable is that reviews say it gets 8 1/2 hours of battery life.

This week's gadget is for the hard of hearing. It's called the Turtle Beach HyperSound Clear Audio System. It provides high directional sound that will beam clear sound to a "sweet spot" for people to be able to hear it. It's not cheap at about $1700, but what's interesting is that everyone else can hear the stereo at normal volume. It's a bit pricey, but when you consider the cost of hearing aids, it suddenly looks more affordable.

David has a problem where his computer shuts off after awhile and he has to log in twice to get it back. Leo says he's had a similar issue with a MacBook. As long as he uses it every day, it's not problem. But after a few days, this issue would pop up. Leo just logs out and shuts down and that solves the issue.

What Technology Will Be the Next Big Thing?

Episode 1276

Oculus Rift went on sale to the public this week. It's a virtual reality headset that has motion tracking in it along with a camera that can track your body's movements. It also has headphones with very good quality sound. For video, it means that you'll be able to look around and see things all around you. Instead of a camera man or director determining what you'll be seeing, you can look at anything you choose. Gaming is another big use case for these headsets. HTC has made a VR headset called the Vive in conjunction with Steam, a distributor of games for PC.
