Here's Gallands 2 cents...

This was really the beginning of the misuse of the 262, as five bomber wings were supposed to be equipped with the jet. These bomber pilots had no fighter experience, such as combat flying or shooting, which is why so many were shot down. They could only escape by outrunning the fighters in pursuit. This was the greatest mistake surrounding the 262, and I believe the 262 could have been made operational as a fighter at least a year and a half earlier and built in large enough numbers so that it could have changed the air war. It would most certainly not have changed the final outcome of the war, for we had already lost completely, but it would have probably delayed the end, since the Normandy invasion on June 6, 1944, would probably not have taken place, at least not successfully if the 262 had been operational. I certainly think that just 300 jets flown daily by the best fighter pilots would have had a major impact on the course of the air war. This would have, of course, prolonged the war, so perhaps Hitler's misuse of this aircraft was not such a bad thing after all.
