The two versions will co-exist. However, there is currently a major
annoyance that switching from one version to another can take minutes, as a
partial re-install is peformed. (Rumour has it the problem will be reduced
in the first service pack, but no details have been released yet). Just
remember that you'll need a license for both versions. If you purchased an
Upgrade edition of Access 2007, you forfeited your license for Access 2003.
You'll need to read the EULA (End User Licence Agreement) to confirm, but I
believe that the licence is valid for a desktop and a laptop for the same
individual.

Thanks for the quick reply, Doug. No problem with the licensing issues as
far as upgrading. I'm an MCP and received Office 2007 Pro by attending one
of the MS events launching it and Vista, last spring. It's standalone, not
upgrade.
Great news about the license, too. I will take your advice and confirm via
the EULA, but I believe that you are correct. I'm still not terribly
thrilled with the new O2007 interface (Aren't ribbons for pretty girls'
hair?), but after reading a good deal about it I'm itching to check it out.
Thanks again.
Scott

Further information on this. Following your recommendation, I downloaded and
read the EULA. The relevant section is below, and you were correct. As items
2.a. and 2.b. confirm, the primary user may install a copy on two devices
provided it is for use only by the primary user.

=================================
1. OVERVIEW. These license terms permit installation and use of one copy of
the software on one device, along with other rights, all as described below.
2. INSTALLATION AND USE RIGHTS. Before you use the software under a license,
you must assign that license to one device. That device is the "licensed
device." A hardware partition or blade is considered to be a separate
device.
a. Licensed Device. You may install and use one copy of the software on the
licensed device.
b. Portable Device. You may install another copy on a portable device for
use by the single primary user of the licensed device.
c. Separation of Components. The components of the software are licensed as
a single unit. You may not separate the components and install them on
different devices.
