Given that this alleges to be a beta version and according to its own EULA:
THIS IS PRE-RELEASE, TIME-LIMITED SOFTWARE MEANT FOR EVALUATION AND DEVELOPMENT PURPOSES ONLY. THIS SOFTWARE SHOULD NOT BE USED IN A COMMERCIAL OPERATING ENVIRONMENT OR WITH IMPORTANT DATA.
why do Apple insist on removing any existing Safari 3 install when installing?
If we are supposed to evaluate and develop, then surely it would be prudent to allow a stable version to also be installed alongside for mission-critical usage.
Surely it's a TERRIBLE idea for non-stable, evaluation software to disallow the use of an alternative stable version?
