Microsoft gives the ‘ok’ to kill legacy input devices

According to the latest Longhorn requirements, keyboards and mice must not connect to the pc via PS/2 or Serial ports, and the BIOS must automatically support USB keyboards and mice. The document has some more interesting information. All monitors will have to be at the 16:9 or 16:10 aspect ratios, and connect to the PC via DVI rather than d-sub. The 32bit system BIOS will have to support frame buffers of over 256MB for graphics accelerators, and a 64bit system BIOS will have to support at least 4GB dedicated RAM for graphic accelerators. USB 2.0 ports, and several of them, including a manditory 2 in the front make the list, along with manditory DVD Burners, S/PDIF out with support for 7.1 channels, and Gigabit ethernet, or 802.11 g/a support.

DEV-INP-02 New! Physically removable keyboards and mice connect to the PC by means other than PS/2 or the Serial (RS232) port
Externally attached (that is, physically removable) keyboards and mice must not use PS/2 or Serial (RS232) port for connectivity with the PC.

There is no decision for minimum CPU or memory, but I’m guessing a 32bit system will have to have a 3Ghz processor and 4GB DDR2 ram. 64bit systems will have to be at least a dual core 2.8Ghz chip with at least ~6GB of DDR2 memory. These are my estimates for a desktop pc, for a laptop, a Pentium M compatible, 2GHz ish processor (Dual core will probably required also) with about 2GB memory.

Longhorn better be something spectacular if all this stuff that MS is pushing for is actually needed.

  1. Alas, not only do I use a legacy keyboard and a legacy mouse on my desktop, I am a legacy person.

    I first learned to write code in Fortran IV, and I went to college before they even had computer science departments.

    I am not completely old-fashioned, though. I have a USB optical mouse on my laptop.
