To buy or not to buy.....

Was thinking for such a long time whether I should buy a new laptop. The issued considered involved lots of factor. Reason.... I've already owned a computer at home. I bought it in year 2004. It is a Pentium 4 model with around RM1,600, if I'm not mistaken and it still working very well.

I need a computer to work out lots of thing at home. Sometimes I will bring some office stuff as home work, watching movie, downloading song, surfing Internet to make some work related research, checking email, online banking stuff etc.....

But recently my sister addicted to facebook. From morning to night, she keeps on commenting this and that, superpoke he and she, writing on the wall here and there etc.. She sticks in front of the computer every minutes when she is at home... And every time I requested to use the computer, she will definitely show a black face. As the computer is funded by me, I always think that I have the priority to access it, but here is not the case...

As a conclusion, she suggested me to buy another laptop so that we can use the computer separately. Such a brilliant idea, but.... the new laptop is also funded by myself. Just feel abit unfair... That's the reason why I'm still thinking whether to buy or not to buy???? Any comment??
