Those reviewers should try and remember what the iPod Touch was like when it first came out. There wasn’t a lot of apps available in the iTunes App Store yet and the software was buggy, slow and used to crash a lot. Looking at the Zune HD now in its initial release, I can honestly say that it had a better launch than the iPod Touch when it comes to OS stability.
It’s certainly a bit early in the game to start comparing both devices due to the fact that Zune’s Marketplace just launched, still isn’t open for developers and, more importantly, lacks content. People need to give the Zune HD some time to fill its Marketplace as well as for Microsoft to start selling it internationally before they give negative reviews and fill the blogosphere with their Zune criticism.
