Hello folks, I've recently purchased the 2013 11" Macbook Air to have it as a real mobile machine and this things is extremely fast. As a desktop machine attached to a Thunderbolt 17" I have an early 2011 MBP 2.3 Intel Core i5 with 16mb of ram and 1tb 5400rpm. Of course the Macbook Air is 10 times faster and a joy to use while the MBP is slow as hell and beach balling every minute to the point that sometimes I have to wait a couple of minutes until I can get back to work. I want to get an iMac and hopefully a new refresh will come soon and I can have the iMac for work as main desktop and the Air for mobile purposes. My question is if it is worth it to get an SSD like the Samsung 840 Pro to reaplce the slow 5400 rpm in the MacBook Pro to speed that a little bit or just save the money and get the iMac? I think it will feel awkward if my 11" 2013 Air is going to be faster than my main desktop machine. I could just use the Air attached to the Thunderbolt until I get the iMac too. I'm just not sure if is good or not to throw 200-300 on an SSD. I have a service battery signal too on this machine. Any advice? Thanks!
