I would love to have a Framework laptop, but there is no guarantee the company will be around as long as, say, Lenovo, Dell, Apple, etc., and I would hate to get used to being able to customize on the fly, then have to go back to a run-of-the-mill laptop just because Framework went out of business.
Better to have loved and lost then to have never loved at all. Why not buy the Framework, support the business, and have a laptop that's making you happy while it's around?
There's no guarantee any company lasts forever. What's the point in not using something now because it might be gone in the future?
In the worst case you would have used your Framework just like a regular laptop from Lenovo, Dell or Apple. You might not gain much, but you also don't lose anything.
