New laptop for 10 year old

[mac]

Am based out of India, can anyone suggest what configuration and brand should one go for. His main use would be internet access, school projects, song and movie downloads, photo down/uploads, movie downloads and games. I am hearing Dual core is outdated and we have i3,i5,i7. Which one has HDMI cable, memory stick slots and is more user friendly. There are choices of brands here like Vaio, Toshiba, HCL, Dell and Acer. Appreciate your knowledgable thoughts
