  • IPv6: Trillions of new net addresses now possible
  • What to Expect for IPv6 Launch Day
  • Many major ISPs and Internet companies permanently turned on IPv6 today.
  • So what?
    • IPv4 doesn't go away. It will operate in parallel for the foreseeable future.

"Hey Tom, Iyaz, Sarah, Jason & Guest

Tom was discussing the limitations of Windows RT on ARM chips, but I have to point this out. Almost all the limitations of Windows RT are around the desktop. You've been able to buy x86 Windows tablets for years. So why haven't they sold if they're fully functioning tablets? Well, turns out, no one wants to use a desktop interface on a tablet. So while Windows RT can't run desktop apps, I don't think anyone cares at all.

Tom wasn't the only person to say this, though, which I think is interesting. Several tech news sites have made similar comments about not being able to fully utilize the desktop, even though for years they've criticized Windows tablets for using a desktop interface. Very interesting, if you ask me.

Love the show, Jacob"

"Panasonic is introducing a TOUGHPAD to go along with their TOUGHBOOK laptops. I've used the laptops and, while not the best performance, they are incredibly durable. Now they are going into the tablet business.

Our sales rep sent the attached as a PowerPoint and told me it is public information, so I'm not violating an NDA.

Obviously, this is for a niche but I thought you might want to check it out - ALibertarian"
