New Operating Systems and DriveSharp

I enjoyed your columns on Windows 7 and Snow Leopard upgrades, but I’m wondering about the case of a Mac user who runs both platforms, e.g., Leopard and Windows XP or Vista?

Such a user would be able to upgrade to, and run, both new operating systems on the same Mac. Microsoft says Windows 7 will be licensed to work within a virtual machine on a Mac—a faux Windows computer—just like XP and Vista can. Apple also plans to offer Windows 7 drivers for its hardware after the new Microsoft system comes out on Oct. 22, so that users who wish to use its Boot Camp system for running Windows on a Mac can use the new Windows.

You can choose to keep running older versions of Windows on Macs equipped with Snow Leopard, or, presumably, run Windows 7 on Macs that still run Leopard. But note that if you do upgrade a copy of Windows to Windows 7 running on a Mac—even if it’s in a virtual machine—you must follow the same, sometimes painful, process that faces owners of standard Windows computers.

I am color blind and am wondering if the DriveSharp driving improvement software you reviewed last week involves identifying colors as part of the learning process.

Yes, it does. Both of the program’s training exercises, which hone users’ abilities to track multiple moving objects and to expand their fields of vision, do rely to some extent on distinguishing colors.
