My laptop is beast but my desktop is my baby; gets most of the attention and is frequently upgraded... Mainly because its cheaper than upgrading laptop parts and this computer geek has never tried to replace any hardware in a laptop yet... XDDDD
If there's a power-cut, your laptop still carries on working whereas your computer will turn off immediately and you will lose everything that you didn't save!!! So laptop, hands down. And you can take it anywhere with you as well.
