Hey, I know there is another thread debating the merits of Apple ridding the notebooks of DVD drives, but I wanted to ask something a bit more practical here so please do not turn this into a debate of whether or not all drives should be removed. My question is, has anyone done this for themselves? And if so, - Did it impact battery life? - Did it make the unit much lighter? - Did it make the unit run much cooler? - Did it make the unit run more quietly? - Does it "feel" weird or unbalanced now that the drive is gone? I was strongly debating getting either a new MBP 13" or a MBA, with the only real pro of the MBA being its weight (now that the MBP has the SD slot, which I would definitely use, the 7 hour battery, the better screen, and overall better specs for the money). But if removing the drive removes some of the weight, maybe it will be more comparable to the Air? I think a slightly lighter, cooler running MBP 13" would be even more perfect than the stock unit. Also, has anyone used one of those replacement kits that gets rid of the DVD and puts in another internal HD? I guess if removing the drive doesn't make it cooler and much lighter, than RAID'ing 2 SSDs together would make it much faster.
