laptop computers

My sister is looking for laptop computers for her children. She asked me if I could go with her at the mall today but I am not sure if I could go with her because I need to finish something. But as soon as I will finish my entire task, I might to go with her. I recommend the desktop computer since most of the time she is on the computer. Laptop is only good for checking emails and other small stuffs. But if you want a heavy duty, desktop is the best.
