My thoughts...
I replaced my 13" C2D MBP (2.26GHz mid-2009) with a 2.3/16/256 MBPR which arrived on Tuesday. Having had a couple of days with it I feel I have made the right choice:
(1) the old SSD which I had in my previous MBP runs at 150MB/s+ over USB3 to and from the MBPR, which means that any media I could wish to run will be to all intents and purposes as quick to load from there as from the internal SSD . So, for the £300 the bump to the 256 would have cost (allowing £100 for the 2.3->2.6) I could easily buy two 256Gb SSDs and USB3 caddies. Win.
(2) My main work machine, a late 2010 2.9GHz i7 iMac 27, has a 256Gb SSD and a 1Tb HDD in it. After 18 months of use, the SSD is still less than 60% full, and I could almost fit all that's on the 1Tb HDD in that remaining 40%. So my absolute data needs are currently well within 256Gb.
(3) I wouldn't want to store movies or music on my MBPR - it's really for work - and I would rather use the NAS drive (connected to the Mini) for these sorts of things as that way I can watch on the big TV.
Maybe, just maybe I might change my mind about this, but because USB3 (and I presume the Thunderbolt ports) are fast enough to allow effectively seamless external storage without obvious performance degradation, I'm not worried.
