I'm just too "Old School" to go 10k between oil changes. I took my MkVI in at 2500 miles for the courtesy check and had them change the oil (cost $65). I considered that 2500 miles a break-in period. I'll change it again at 5000, and then every 5000 thereafter. I'm leasing, too, but I did so to keep the initial cost down -- I very likely will be keeping my car, so longevity is an issue. Anyway, 10k just doesn't feel right to me. Like somebody said above, oil changes are cheap insurance for a high performance engine. For all that it gives me, I think my GTI deserves the best treatment -- he'll get fresh oil every 5k.
