There are some cases where time zone information is absolutely critical. For example: When scheduling a video conference that crosses national boundaries.
A few hours ago, Google sent me a reminder about today’s LinuxBarbados meeting. The group meets via video conferencing software over the web.

Fortunately (and contrary to what the Apple literature says) it is possible to upgrade the SSD in a MacBook Pro. RAM is different because the MBP’s RAM is soldered to the logic board. But the SSD plugs into a socket. The SSD upgrade path is well-documented on YouTube and elsewhere.
