I really like the idea of being able to add SSD down the road. I just can't decide if it's worth taking short term hit by ordering a new system with the 256GB SSD drive installed just to preserve the Warranty? It's $540 to add the 256GB SSD drive using the Education Discount. Those drives seem to be selling for around $400. So it's approximately $140 to have the SSD core components installed plus the price of whatever SSD would be used to replace the poor longterm performing stock Apple SSD...... Or OWC can Add and SSD drive for you starting at $449 for 120GB drive. My only concern is this would totally void your warranty. What are other people thinking of doing? Am I crazy for even wanting to have SSD? I don't think I need it right now but I like the idea of being able to add it later as prices come down.
