Hi. If I sell my 15" 1.5 Ghz. 80GbHD 1Gb RAM Combo drive Powerbook now as it has 4 months warranty left and is in immaculate condition, could I ask £900 for it and how much do you think I would get at the end of the warranty? I guess it's also worth bearing in mind that the new MB costs £749 for the basic model and £899 for the mid range one so am I right in even thinking at this price? What do you all think?
