Not sound advice. Quoting a batch reply I received from Purism regarding the same topic:
Hello Librem 5 Backer with questions,
Due to our small team and the large influx of inquiries since the Batch Selection e-mail, here is a quick rundown of the common questions and their answers. We will be adding these to the Batch FAQ soon.
- Why wasn't Fir listed as an option in the Batch Selection E-mail?
Fir is a phone in the future, the 2nd revision of the Librem 5. We mentioned it to be transparent for our product roadmap and are fine if people select it. But, as it's a completely different phone model, the timeline given for shipping is a rough estimate. It will be a 1+ year before release.
If you select/selected Fir as your first option and end up changing your mind down the road, you will be eligible for Evergreen once it starts shipping.
- Will the chassis on the early batches be plastic or metal?
The chassis for all batches will be aluminum. First few milled then made from molds.
- What is milled vs molded aluminum?
Milled is when one takes a chunk of something, in this case aluminum, and uses rotary cutters to shave material off until the chunk is in the shape of a phone chassis.
Molded means one pours liquid aluminum into a rigid matrix, or mold, to form the phone chassic.
- What is the quality of the chassis?
As per the Batch FAQ, it will be a high quality chassis, just a difference of manufacturing technique and slight tweaking between batches.
- What are the differences in switches and can I buy the newer ones for an older batch?
The difference is mentioned in the Batch FAQ (link below).
Whether one can purchase or change switches will be known at a later date.
- When will Purism be sending out the e-mail to confirm shipping address and modem selection?
We will do so before we begin each batch shipment.
- Will you have issues delivering the Librem 5 to certain countries since the phone won't be CE & FCC certified?
As mentioned in the FAQ, the radios are already certified. We do not foresee any issues with shipping the earlier batches due to the nature of those batches.
