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?
One good reason why computers can do more work than people is that they never have to stop and answer the phone.
