I received shipment of the some 1/2"x3/4" tubing earlier this week and wanted to post my impression for anyone else who was thinking of using Nalgene tubing as a Tygon substitute. Firstly, it is very clear, better than the cheap PVC I bought at Home Depot for testing. It does have a slight memory, but it's no problem to "re-train" the tubing to a new shape, and is really quite easy to work with in general. It can take some pretty sharp turns (the minimum bend radius I've been able to get is 1 1/2"... though I bet I can get less with a bit of heat). Also, I am able to use this stuff without hose clamps on both 1/2" and 5/8" nominal barbs without leaks on an extended leak test that I ran... using both brass and PVC fittings. All in all, I can say I am very satisfied with this tubing, especially when you consider that I paid a lot less for it that I would have for Tygon.
