Well, i do have Atoms running here with 32bit and PAE and 8 GB of ram. Even the rather slow N270 does support this. The Intel board D525MW (which includes a soldered D525 Atom) officially (intel website) supports only 4GB but will run fine with 8 GB. Of course there might be older Atoms that do no

Hi Thomas, I agree with your reasoning - it is very practical :) However I am not sure what you exactly call by "software". AFAIK the BSD kernel has been 64 bit enabled and capable years ago so from that point of view this is mature. For a change various processes for example RPD last time I che

Yeah, that is clear - my original point is: I do not trust the 64bit software - I have more faith in the 32bit software. As per now, it has equal cost to order an MX960 with 32b-4G-RE or 64b-16G-RE. So of course I would order the bigger RE but only if I can use the the matured software... To
