Hi I am a PC user for over 15 years but after trying out my roommates Mac I decided to give it a go. My PC is currently broken and I am therefore urgently in need of a computer because my term has already started. I want a powerful computer that will last but he tells me that the only customizable things like glossy screens are unnecessary and that the standard issue ones like a 2.5 to 2.6 GHz and 2ish gb of ram will be fine. I am willing to go to the largest store in San Francisco (which is nearby) and pick one up. Do you think the store will have them ready by 10AM when it is announced or am I better off getting one online with a bit more customizability? Thank you!
