Why an atom? There’s literally never been a nice atom machine made, they are literally sold to companies who don’t want to buy intel’s nicer power efficient chips, atleast that was the strat back in the day. A i5 540m laptop for example would have been a mid-high end laptop from the era, have the same designs and aesthetics, might even be able to find it in a similar/same chassis as the atom laptop your thinking of.
Unless you just wanna stare at the machine, don’t get an atom laptop. The Core variants from that era are literally 10-(infinity)x faster.
