.3megapixel with he led backlight
if you want the 2megapixel cam you have to stick with the cathode back lighting
im guessing the offer the 4cell to keep the weight under 4lbs so it can be considered a ultra light, the the 6 and 9cell up the weight, i believe the 9 cell jumps up to 4.7lbs
also a review on pcmag
i dont know much about draft N, but if i have the N card in the laptop, is it backward compatible say if i go to a hotspot that uses B or G?
Yes, absolutely. N cards are fully backward compatible with b and g. I have an N card in my M1210 connected to a b/g network.
