It's like saying: I want to buy a new car but I'm not really sure what I'm going to use it for..
How much are they willing to spend?
How old are the kids and what type of homework do they have? Grade-School or College? Are they artists which might require graphics improvements or are they accountants?
Do they play graphic intensive games on the computer?
Either way, right now is a good time to be looking for computers.. Check the newspaper advertisements for "Black Friday".. You can frequently find great deals.
Hope this helps and let us know more.
This question is for a friend. She has an old Windows '98 system (inherited) and wants to buy something new to use and for her kids to use to do homework. At this point she has no real idea what she will be using her computer for in the future. What would you recommend she buy? (What specs should she look for?) Thanks!
