today, my temps just spiked. typically with just safari/word/excel, it'd be in the 50s. today, it hasn't gone below 70 with just those apps - and has been up to 90. the bottom is extremely hot, the top is hot to the touch in the top left corner and in between keys on the left side of the keyboard. what the hell happened? i can't take it to applecare yet, i use it in class every day..
