I read a review which had a text which was telling about a 3g modem feature in One: "Where the One gets one over the Eee PC 901, however, is with its optional 3G/HSDPA adaptor. Behind the battery pack, there's a SIM card slot into which you can plug your 3G SIM for go-anywhere Internet access." So what does this actually mean? There is a SIM card slot behind the battery pack but didn't dare to stick my card in because there seemed to be no way to eject the card out of the slot. Does One have a built-in 3G modem. I do have a SIM with 3G-operation and would much like to use it with my One.
