I have to agree with the two above posters.
I too have questioned SSD or HDD? Honestly, company purchase or not it's one of those things where I think I am blinded by the fact that the money is already out of my account since I returned my MacBook. The refund came on a gift card and technically it'd look like I was spending a lot less if I paid the difference out of pocket. We both know that's not the case.
For my computing needs, which I would say are even less than yours since I have a MacPro sitting here, I do not need the SSD. The SSD is great for people who travel often, there's that nice layer of protection with the "no moveable parts" bit. Then of course the performance of launching applications is nice. I would say to some degree there is other performance enhancements, but not enough for me to warrant a $700 price increase.
As it was also stated, there is a lot more you can buy with that $700. Accessories, copy of windows if you need it, bags, dinner for some chick, etc.
I don't think you need it personally, but if you have the money and you're not opposed to shelling out the cash then get it. If this is all coming up because the bastards at Apple are delaying the HDD model on account of the increased SSD model sales (their plan worked) then just wait.
