I didn’t buy my Framework (i7-1165 which really seems to be the sweet spot CPU, 32GB 500GB Gen 4 SSD.) just for the promise of repairability alone. It was for the freedom to chose my parts. I picked what memory, drive, and wifi card to put in. And I saved $300 by putting it all together myself. My total package was $1400 (I already had a windows 11 license, no need to buy one.)
To give you an idea, I chose to put in 32GB of RAM over a 1TB SSD because I could get a faster smaller SSD for less money. See? A choice.
I have owned dozens of laptops and all of them, with the exception of my Macbook Air M1 have all been things where in 12-18 months, I need more and then have to replace them. Not that there is anything wrong with them, but for my use case, faster means better productivity. My goal with the framework is to have a computer than can scale with me.
So for your case, I would point out that that Lenovo in that configuration for $700 is a deal. However there are three more things to think about as well.
the first is that The Ryzen 7 does not support PCI-E Gen4, and I also believe that depending on the model version, the top end of memory is as low as 32GB of ram? The 1135 you have is capable of 64GB and PCI-E Gen4. There is a tremendous speed difference. At my work, we all got $1800 to spend on laptops and my coworkers all got 2020 gen Dell XPS15s with the discreet graphics. But because Dell did not give them a gen 4 option, my drive is literally twice as fast.
Second, I made a specific choice to sacrifice dedicated graphics for the lighter weight and better thermals. As was said everywhere else, the thing about choices is that it is nice to have them.
And then the third point. If Frameworks works out, next year they should release alder lake boards and possibly Ryzen boards. If the promise is true, and I hope it is, the dream should be that you can upgrade to that mainboard, and then take your old one and 3d print a case for it or buy one on the market place to use as a small NUC. The mainboard is self contained and will boot outside of the laptop. Try that with your Lenovo…
To me, the first and second were overwhelming points in favor of Framework, and that does NOT get to repairability, ease of upgrade paths, ability to freely pick and choose my wifi, and reconfigure my ports as needed.
The third one is a promise and hoped for, but it should not be a reason for buying now. If I were you, I would just get another 8GB stick, and throw it in your framework. Because thunderbolt 4, PCI-E 4.0, Port reconfiguration, ease of upgrade and repair, and the better screen are worth the trade off of the ryzen 7’s better performance.
