The reason I keep thinking, though, that I should KEEP the 1.3 I preordered is "future proof" (i know there is no such thing, but more like "future better"). OS X updates and the like. Keeping up with new code for Safari. Etc etc etc.
If by future-proofing against OS X updates you simply mean that if OS X in the future ends up running slower on older machines because of higher realistic base hardware requirements, then okay, fine...maybe. But if you mean you are hoping to protect against your computer being completely unsupported by a future version of OS X at some distant date in the future years down the road, you should know that Apple has never, to my knowledge, discontinued official support for only a subset of a generation of a particular model of Mac in any given OS X release. If a future OS X 4-5 years from now ends up not supporting 1st-gen rMBs, it will fail to support ALL models, not selectively fail to support the lower-clocked ones while continuing to officially support the higher-clocked ones. So holding onto a 1.3GHz model will give you no advantage in that regard.

2. ghz is not going to provide much future proofing on a macbook. I doubt there will be many program released in the future that will only run on the 1.3 but not the 1.1.
 
Save the money for future upgrades.

You'll get more bang for your buck by moving the upgrade schedule up with a machine like this. The price of these things is pretty much guaranteed to move down, IMHO. (I'm not complaining in the least about that, to be clear.) Between the ridiculous resale value of of Macs, and the likely lower future cost of entry, that $250 will probably go a fair way towards bridging the gap.
 
1.1 is enough for your usage.
1.3 isn't that much more a future proof than 1.1
if you can't run a new OS X on 1.1 at all, you can't run on 1.3 neither,
if you can on 1.3, you can on 1.1 too.
 
Ok, guys. You convinced me to save the dough. I think the "logic" wins out over the "emotion" here.

Thank you all! 1.3 order cancelled.
 
For the love of God I've been on these forums for almost a day with the 1.1 v 1.3 dilemma.

Think will going to hit the button on 1.1 too. Not necessary because it's cheaper but becaue for my use I'm convinced if you gave me two machines and asked me which was which I probably wouldn't be able to tell you.

The .2 difference with everything else identical really can't make it that much faster.
 
I've just gone with the base model and I'll just upgrade to the newer version in the next 2/3 years. It should hopefully be a bit cheaper by then too.
