No the laptop is actually huge. The screen is about the size of my desktop screen.
Here are some tips.
1. Run Blockland in a window
2. Set the resolution to something like 800x600
3. You should still have an antivirus. MSE is a free, lightweight and effective antivirus you could try as an alternative to McAfee.
4. You can use some programs such as
Ccleaner to disable startup processes. (Note: Be careful about not disabling processes you do want, such as the hotkey manager, your antivirus, and the sound/video controller(s))
