Here we go. Perfectly timed with this week's festivities, Motorola's split, wherein one become two (a "reverse Spice Girls," if you will) is crossing the final t's and dotting the remaining i's. The Wall Street Journal is reporting that by Tuesday, the Motorola stock ticker (MOT) will stop trading, being replaced instead by Motorola Mobility Holdings Inc. (MMI) and Motorola Solutions Inc. (MSI, no relation). The latter will focus on public-safety radios and handheld scanners while the former, with a bright new logo, will be the smartphone / set-top box-focused company that for all intents and purposes we mean when we simply write "Motorola" from here on out. It just rolls off the tongue better.
