1. Don't buy ultrabooks. It's one of those ultra-thin notebooks. Don't buy it. Ultrabook has no problem in handling office and audio and video, and it is relatively light, but for boys, playing large games is a bit stretched, and ultrabook is generally not good at cooling.

2. Buy a computer with SSD and hdd. Only one person is not very friendly.

3. Specific recommendation. You can look at Dell's suitcase series and HP's night elf. These computers are cost-effective, well-configured and balanced in all aspects.
