Pardon my ignorance as to how screen brightness is determined (hardware? software? etc?). I have a 17" MBP with an intel Core Duo and the screen is rather dim, especially compared to my wife's brand new MBP. Other than that, this laptop is awesome and I have no issues with it other than wishing the screen was brighter. So, is it possible (without spending what it would cost to get a new computer ) to upgrade the screen brightness? I plan to get a new laptop in the coming months but I have a few software programs that I absolutely have to run on this MBP since it runs SL which won't work on Lion (this biggest is a full SPSS license). So selling this laptop is not an option. The new laptop will be an addition. Thanks for any help in advance!
