Unfortunately, giving a **** about left-handed customers rarely makes a particularly profitable business model, especially given that the number of left-handers who chose to game right-handed for one reason or another dilutes our numbers even farther.
I bought the first RBP when it came out back when, but the damn thing pissed me off so much that I flogged it on eBay... I got so tired of wrist pain from contorting my right hand and so irritated with having all these cables pissing all over my mousemat even when lying in bed! I got a MBP instead to fill the void of being a development machine and also a gaming rig to **** around on CS1.6 and HL2 a little bit. It was nice playing FarCry 1 again though and I think I even tried the CSGO beta on it as well.
That said though, I would still encourage left-handers to try this thing out... I'm more willing to have a go at shifting my standard TGFH config to the right and go with IKJL or even farther from WASD so that I can play comfortably just so that I can have the pleasure of gaming on what looks to be such an amazing piece of kit. Hell, I'd even be tempted to try playing some less awkward games right-handed just for this if it really is as good as this review would have me believe! Luckily we southpaws are all proficient in the art of right-handedness to some degree... I expect we could all do it way more easily than a right-hander could do the opposite... Most of my friends couldn't find their asses with their left hands ha ha
