New computer, and 4Gb Usb. I bought a new ultrathin on G-market(online shopping malll in Korea). It's u200 holic which is made by msi company. I bought beacuse it's good and cheap. and one of the reason it was cheap was that this one is without OS(windows or Mac). I got parcel today and tried to install win7 with usb. But I failed because my imation usb is not capable of windows7 dvd. Imation corp sold usb(4GB) but it was 3.74Gb and win 7 was over 3.8Gb. I was shocked and got angry with this trick. They said 4000802bites to 4Gb. But, in fact 1Gb is over 1000000bites. it's 1024*1024bites which is 2^20.(In computer digit 1and 0are used and 1024 is similar 1000 but involusion of these similar number is not that similar-It;s quite different-. though, I can still make a good use of this 4Gb usb memory, I disappointed to Imation corp. Next day, uhm...now today(it's 1:32Am), I'll borrow 8Gb(whch is not real 8Gb too, I guess.) and try to install again. I hope that I'll be good at next step of installing OS so that I can use my ultrathin the day after tomorrow. And hope corperations to make real 4Gb usb memories.
