soldered

Not like MBP with soldered RAM, soldered SSD, weak ventilation system, no LAN and just 2 USB ports.

Since the RAM is soldered on, it practically forces me to buy a Mac to get enough of it...

The card is soldered in on the screen side of the mobo.

I believe the RAM is soldered in, so it's not like you could replace it later.

I believe the RAM is soldered on, upgrades may not be very feasible.

Isn't 'stripboard' the technical term for the soldered type of prototyping board (often known as veroboard in the UK)?

You can get away with doing it if you support the soldered end against vibration, but you should do that anyway.

The voice was captured by a crappy mic I soldered myself from parts and placed on a wardrobe.

Properly crimped connections will stand up to a good deal more vibration (and are pretty much gas-tight, staving off corrosion) than soldered connections.

I see one major downside to this machine: it has memory soldered to the motherboard.

Macbook Air 2012 models with 4GB soldered RAM ran fine on Mavericks and XCode 6, until Apple decided the newest XCode 6 to be Yosemite only.

The latest Mac Mini (2014) I saw had soldered RAM and a slow processor, so older used versions should be even more popular....

We're already seeing that with integrated, "soldered-on" graphics cards, and with frameworks like OpenCL, and higher-level abstractions like Theano, Torch7, etc.

When I was young, we wrote all our code by hand using ed in Sanskrit, printed it out and hand soldered into hardware using tools we made by smelting our own iron!".

Soldered ram should actually produce a tiny but less heat, since you're eliminating the resistance of the connector on the system board and the circuit board the ram would be attached to, to slot into the connector.
