While the MacBook 13" Late 2008 model unibody aluminum is a good machine, it probably won't last for ten years on and still be functional across the needs of a changing internet, email, and any video hardware or software that will be coming out in the next few years. Or even now when looking at the cutting edge of today that will essentially be near obsolete in less than the next five.
However the video graphic support in the above model computer is limited because it shares RAM with the graphics chipset; so it is not the best model for video editing, but may do OK depending on the source of the video and the depth of effort required to edit it. Applications and duplicate layers of imagery take resources.
A good place to look at specifications and compare them is online at http://everymac.com and also to get and look through the database once downloaded from http://mactracker.ca There are older refurbished models at times from companies who repair and restore portable macs for a living, one site to look into & compare is wegenermedia.com and there are others. If one could get a great deal on a previously owned MacPro with 64-bit EFI architecture, it could support better graphic cards and render, process, and do many tasks very well. And get one from an owner who upgraded to a late model MacPro.
However one may need to be able to upgrade and troubleshoot the beast oneself. At least the component parts aren't all in one package, and that can be good when needing to replace a display, keyboard, mouse, trackpad, graphic chip, upgrade RAM, and other things. Even a Mini can be a fair setup.
However there are nice things about a portable Mac computer.
It is portable. It is light. It doesn't use much power. It can support
an external display (to a point) and a few other bright points.
The real question may be: what may a 2008 anymac be worth (?) in 2024.
Hopefully this helps somewhat.
Good luck & happy computing! 🙂
