  • Good.

    About every 5 days, my wireless-n connection slows to a crawl with about ~18kbps throughput. A quick reboot solves the issue, but very annoying. And I have noticed a few times when the virtual keyboard either pops up/doesn't when it shouldn't/should. Those situations are minor though.
  • Miracast a Bear

    I can do Miracast alright on my SP1 but the external screen just seems to freeze when I connect through Miracast. Hopefully these updates will fix this problem.

  • Mixed Bag (As Usual I Guess)

    WiFi is more stable: short sleep cycles (5-30 minutes) no longer drop WiFi connection, but deeper sleep (more than an hour) requires starting and stopping the Marvell card to reconnect to WiFi. Worse is the insane battery drain during sleep cycles: 17% drop in four hours from power plug to wake; used for an hour or so, then back to sleep (using Power Charm) and 8 hours later dropped another 35%; basically 4.2% per hour when in sleep - that's a real game LOSER at this point. You have to shut down completely or force hibernation (requires a lot of hoops to set up) to avoid extreme battery drain.

    Surface Pro 3 - the device I love to hate (or is that hate to love). It is so frustrating a great device and a PITA at the same time.
  • July Surface Pro firmware Update issue

    I am getting a little tired of the numerous and repeated issues updating Microsoft systems of all types and flavours.

    Today I updated my Surface Pro 2 with Windows 8.1. After that my pen no longer works. Dead as a dodo although touch works. No errors in logs although the firmware update failed on its first try, tried again and then succeeded - allegedly.

    What has happened to Microsoft's quality control? I have had issues with Exchange 2013 SP1, SharePoint 2013 SP1, System Centre DPM 2012 R2 and now my Surface Pro 2. This is not good enough. I am close to ditching the Surface Pro 2. I don't want or need to spend 4 hours trying to resolve a problem caused by a firmware update. Fortunately my IPad does not have these issues. Perhaps that is telling me something?
    • Surface Pro 2 Issue

      Oops my post needs editing. I meant to say my Surface Pro 2 which already has W8.1 happily working was busted by a firmware update. I was not updating the Surface Pro 2 to Windows 8.1
