Yeah, soldered parts; but most manufacturers sell a windows pc with emmc storage that is pretty cheap. I have an older HP version with 2GB of Ram and 16GB eeMC storage. It fits in the tablet pocket of my backpack, is super light, long battery life, and runs opensuse like a champ, even with KDE.
EDIT: emmc, not eemc.
The only problem I have with soldered parts is soldered RAM. Everything else can be worked around with patience or external parts, but once you don't have enough RAM to run a web browser with a single tab open to a common website, you're constantly page faulting.
I'm not sure whether this is planned obsolescence, or just the consequence of consumers who don't know or care about upgrading their device to keep it current.
