She clearly hasn’t contributed much as a leader. It’s easy when you have a genius with a vision telling you what to do. It’s another thing entirely when you’re given the reins but lack the talent and vision to lead. Hence, my comment about Jony being able to contribute as an outsider (new iMac) while the rest of the lineup is just a rehash of Jony’s old designs during her tenure.
To be fair, most of Jony's designs are also iterations on his own old designs. For example, MacBooks basically had the same look and feel with the unibody designs since 2008 for MPB and 2010 for MBA with minor iterations in thickness and dimensions until we started seeing the more rounded design language in the Apple Silicon Macs. Once a design language is established and gains popularity it's not always necessary to introduce new looks every generation.
