Easily... pick the 2.4
the $300 difference gets you
- backlit keyboard - may not think much of it but once you have it, it's hard not to have it
- Faster processor - with the new DDR3 ram, this 2.4 screams, especially if/when you upgrade 4Gb ram. I notice that it's quicker right of the bat with processing photos from my camera or iphone. noticeably faster than my 2.2 MBP
- larger HD - you can never have enough HD space - 250Gb is a nice size even if you don't upgrade.
i got mine and within a day, added 4Gb + 500Gb drive
My rule, always buy the most computer you can afford at the time you needed it.
Good luck!
