actually Lenovo G505S has more freedom in some relations, if compared to Chromebook R13 : for example, G505S does not require blobs for WiFi and Bluetooth if you replace its' preinstalled Broadcom half size mini PCI-e card with Atheros AR9462 (which has 2.4 GHz + 5 GHz + Bluetooth and is top-of-the-line ath9k card) and its' price is just $8-$10 with free shipping included ;)
Well, I don't think that Wi-Fi is really a big deal compared to having coprocessors that can only run proprietary software, in addition to proprietary graphics init along with a proprietary EC.
You can easily use an external ath9k_htc USB dongle on CrOS devices instead of the internal one, which solves the Wi-Fi situation easily.
There's hope for the G505s though and I truly hope it can get close to the current freedom status of ARM CrOS devices! (And I'm still working hard to improve the EC situation.)
also there are some great technical opportunities which chromebooks do not have - e.g. you could replace WiFi mini pci-e card with double SATA ports RAID card, or you can install 16 GB of RAM because G505S RAM is not soldered ! Still could get G505S in good condition at many USA / European markets, e.g. yesterday at eBay I saw G505S based at USA which costs just $95, also UK-based in nearly mint condition ;) Also there are a lot of spare parts available, which helps to ensure the long lifetime of this great performance quad core laptop ( Chromebook is not even close at performance, as far as I know )
Yeah, those are definitely nice technical features (but they're not freedom- related)! I also have a bit of a hard time with devices I can't replace broken parts for, because they're all soldered onto the same board!
Cheers,
Paul

I am looking for a new portable device available in Europe.
Is it true, that the Acer Chromebook R 13 [1], is the only current BLOB free device? The device currently costs 400 €. Is MediaTek “a good citizen”, that means, do they provide datasheets and work on drivers?
The Chromebook R13 (elm) is very close to being able to boot without non- free blobs. The only remaining blobs are the MT8173 PCM firmwares[0] in ARM Trusted Firmware. I am working hard to liberate them and I'm very confident that it will happen pretty soon.
However, note that the kernel will require blobs for features such as:
- hardware video decoding
- Wi-Fi and bluetooth
- GPU support
I'm also not sure about the status of the PD (USB type-C controller) chip. It might also be running a proprietary firmware (maybe someone from the CrOS team can clarify this).
Also, note that as usual with laptops, there are lots of other non-free components around that are preinstalled on the device, such as the webcam firmware.
Note that ARMv7 CrOS devices (mainly RK3288 and Tegra K1) can also boot blobless and generally require less kernel blobs too. They also have much better upstream Linux support than the ARMv8 ones (which are more recent). For instance, I'm running a mainline kernel on the Tegra K1 nyans, which is quite usable despite some issues that I have left to fix. There's also a very high chance that the GPU will work with nouveau and free firmwares eventually (I'll be working with nouveau developers to try and make this happen).
The Samsung Chromebook Plus/Pro with RK3399 [2] are only available in the USA, right?
I am not aware of it being available in Europe. However, if you're fine with a qwerty layout, they work just as well in Europe ;)
RK3399 can currently already boot blobless but also requires kernel blobs. However, it seems that the boot is currently broken with coreboot master and ToT depthcharge and vboot (I'll be investigating this soon).
Also, the Chromebook Plus (kevin) does have a free software PD firmware.
Finally, note that the Chromebook Pro is an Intel x86 device, so probably not very interesting given what you're looking for.
