Hello. I just got a new Macbook Pro for Christmas. Its the 2.53 ghz, 4gb memory model. I downloaded the iStat Nano widget but Im not really sure if its 100% accurate. Anyway, my question is that it shows that I'm using half of my MBP's memory but right now I only have two programs open: Firefox and Vuze is currently downloading a large file so maybe that is the problem? Im not really sure, I just dont see why only having two programs open would be causing such a memory drain. The file that is downloading via Vuze is 736 MB so I guess that is a logical explanation but I dont really know for sure. Thanks for any feedback you guys can give me!
