I absolutely HATE trackpad oil/wear. I have used many pre-unibody MacBook Pro's (and other laptop models) that have worn trackpads that make tracking VERY hard. But these new trackpads are apparently wear resistant. I have a Moshi cover on the trackpad, but I'm wondering if its even useful. Since the unibody systems have been out for a long time, can anyone report back on trackpad wear. Are the glass trackpads really as good as Apple claims, and thus no wear? I have had a unibody system for a year but it has always had a trackpad cover, and if possible I would like to do away with it as it makes tap-clicking a bit hard. Thanks MR folks!
