Despite being (ostensibly) state-of-the-art technology, I feel similarly about my 2021-vintage MediaTek MT8183-powered Chromebook.
Despite costing sub-$300, its CPU is comparably powerful (according to Passmark) to the Vaio VGN-P588E's contemporary desktop CPU, the Intel Q6600. Of course few PCs in 2009 had 4GB of RAM at the time (to say nothing about the GPUs of the time).
The MT8183-based machine offers a surprisingly capable computing experience, allowing for simultaneous Meet presentation + JavaScript-heavy web application usage, all at that retro computing price point.
Where it ceases to feel like my X61, however, is in battery life. Where the X61 only lasts a few hours of heavy usage with a fresh battery, the MT8183 chugs along for 12+ hours.
