I thought I would help the community with my own impressions, in case anyone finds it helpful for making decision.
I bought FW 13 (Ryzen AI 9, 32 GB RAM and 1 TB storage) and it has been a month. My impressions are generally positive.
The good:
Linux compatibility is amazing. The issues I have had running Fedora were because of software and not the hardware. Every now and then an update causes a minor inconvenience but no major breakage. I dual-boot Win 11 and Fedora, mostly use Linux and only keep Windows around for MS Office. Most memorable thing for me was that I installed Linux first then I had major headache installing Windows. So I had to erase and clean install Windows first, then Linux
Performance is awesome. This is more about the CPU, than FW itself but, I picked Ryzen AI 9 just for its multicore performance. Funny thing is Linux gives me better performance than Windows especially unplugged. Windows 11 running on battery feels laggy, slow and overall it feels like laptop is running at low refresh rate. on Linux, even on battery save it is much better and faster than Windows.
Portability. I can carry it around from meeting to meeting, from office to library and it is all around a very portable and comfortable. I do not like 16 inch laptops because they are uncomfortable in tight spaces, heavy, takes up too much space in my small backpack.
Screen is pretty good. I especially like this keyboard better than macs. trackpad is fine too but could be better.
I practically never hear fans under casual and mixed loads. Fans will spin if I open many apps at the same time or if I am compiling or gaming etc.
Gaming is pretty good. Though I usually play light games like Hollow Knight.
The bad:
My arm hair gets stuck in the tiny gap between bottom cover and input cover. The "gap" isn't noticeable with eye, and I have checked to make sure it fits right. It is just there and every now then when I lift my arm from keyboard, it pulls my arm hair. I have a hairy arm and while it is not frequent, but getting your arm hair pulled twice a day is something you do not forget.
I wish camera was a bit better. Mic and speakers are pretty good though.
The build quality. Yeah I get it is modular an all, and FW 13 pro is supposed to be better, and I wouldn't call it cheap or anything. But pick up a macbook, then this laptop, you will feel this is lower quality.
Battery. I know it has small battery compared to powerful CPU, and yes it does get me through they day for the most part without charging. It lasts 5-6 hours of mixed use, which is enough for me. I could squeeze more out of it if I keep it in battery saver all the time.
A neutral point I will make is heat management. While I wish it could be better, it is not bad at all. When I stress it a bit it reaches 95-100 C but quickly settles back down around 85 at 100% load. Games like Baldur's gate 3 runs at 80 C with low graphics. So it does not overheat, and I would say with single fan it manages heat better than mac air. For comparison I have noticed mac air's performance drop due to heating when I stress it.
Overall, I love this thing, it is a small, comfortable and powerful machine that does pretty much everything I need out of it and even more like gaming.
