You remember the one which mysteriously doubled in price when it came on the market, is now £220 plus from manufacturer Asus and its distributors, although one UK distributor is asking around £250. They're in short supply. Never give a fellow Brit an even break, I say.
But it may all end in tears for rip-off merchants because cheap-as-chips manufacturer Everex is about to bring out the Cloudbook http://www.crunchgear.com/2007/12/10/everex-takes-on-eee-for-cheapskates-everywhere/.
It is, in the words of one previewer, a 'tiny, small, dwarven laptop' which will have a proper hard drive, a touch screen and the usual stuff at around $400 – which is what the EeeePC costs here.
Other manufacturers are eyeing up the market for tiny ultra-portable notebooks (Apple included although it hates that concept of inexpensive) so if you wait a month or two the EeeePC may have reverted to its originally-promised price to fend off the new competition. At the moment you can buy a fully featured, basic but proper laptop with (relatively) lots of memory for only £75 more.
