At least these 99 USD/99 EUR laptops exist.
Today I saw an ad of a local supermarket advertising such a "thing":
Jaytech Jay-book 9901

128 MB RAM, internal 2 GB Flash, SD/MMC slot (supports up to 32 GB)
Mousepad, WLAN b/g, 3x USB 2.0, internal speakers, 1800 mAh battery (expected lifetime: up to 4 hrs), weight: 590g

Price 99,95 EUR (vendor's claim: MSRP 199 EUR, which is a lie (link to importer's press announcement - german language) .)
