Not really -- swap is good even if you have plenty of RAM, because it allows more caching. Paging in the exact portion of a cached file that's needed is significantly faster than rooting through the filesystem to read it.
I do agree that it's a bit of a cheat the way they go on as though it had 1GB of RAM, but I'd want significant swap in any case.


It remains to be seen if having SWAP on the N900 will ultimately result in lag and a worn out NAND.
I don't think it really remains to be seen, unless you've some reason to suspect the eMMC will wear out faster than the 1GB in the N810. People have been using swap on them ever since they came out, and I've heard of no problems. Actually, since the swap region is a smaller fraction of the 32GB than of the 1GB, it should last longer.

Over the expected lifespan of these devices its probably impossible to wear down the NAND, although does eMMC even have wear leveling? I was under the impression eMMC, MMC, SD, etc did not.[/quote]Yes, the MMC spec requires wear-leveling built-in. I've heard that some cheap cards disregard the spec and don't have wear leveling, but I've no clue the veracity of this rumor. (FWIW, I heard it in conjunction with couterfeit name-brand SDs.) I'm sure the eMMCs Nokia's using are genuine and conform to spec.
