momentux xt 500 ssd/hd hybrid and 1333 2 x 4gb ram perfect combo, unless you have enough dosh go for full ssd, but some of the ssd still unstable my 2 cents

@ Kernkraft400 , Actually i have never used more then 320 in all my laptops as i always have a 1tb external always hooked up and when im away from desk i rarely use the media files

as i mostly work with excell so difficult to judge but i do agree ultimate twek would be
SSD main drive
700 gb at optibay
2 x 4 gb1333
But i like my setup right now

500 gb momentus xt
2 x 4gb 1333
1 TB my studio external (at desk)
320gb in enclosure (ori apple drive)

What ssd did you use ?

I had it on my 13 i7 works great better then standard hd in boot time etc but not as good as ssd, can't even compare to my MBA now

an excuce to charge couple of hundred extra

once you go mac you dont go back!!
