Numerous Windows users have now had time to try out Apple’s iTunes — and reactions are ranging from unabashed praise to complaints of crashes on Windows 2000, reports CNET News.com. Apple declined to say how many people have downloaded the software, but an executive said that it has been very popular since its release yesterday. “The downloads have been going full tilt constantly,” said Peter Lowe, Apple’s director of marketing for applications and services. “We’ve been delivering a lot of Windows software over the last 24 hours… We’re really, really pleased with the reaction.” He also addressed bugs: “We have seen some isolated reports of people locking up after restart. We are investigating that.”
