Too long lived... for the manufacturers
Bought an eee 4G at Christmas after it's first release. Had Xandros on it, Ubuntu Netbook Remix, Puppy, then Gentoo. I'd still be using it now if I hadn't got someone else's eee 900 when they bought a newer Samsung netbook, but that eee 900 is my main computer for home use. At work I've got access to machines with 16 cores, zippy SSDs and 128GB memory, but I don't need that at home.
Saying that, I would have bought an OLPC XO instead of the eee, if you didn't have to have a US mailing address to use "buy one give one" at the time. I'd still buy one or maybe two now, if they were generally available to the public. C'mon OLPC, how about it?
