I have $800 worth of gift card to spend it on either a laptop or desktop. There is already a desktop in the house but my brother rarely lets me use it. My question is which should i get, a laptop or desktop? Which would save me the most amount of money in the long run taking electricity bill, malfunctions, upgrading, etc into consideration. Also, i would like to use it from most important to least: MS office, movies, visual studios, games, music
