Okay, so this is a minor quibble - but as much as I type is starting to be a bit annoying. The palm rests on the cover, due to their felt-ish material is starting to chafe a bit on my palms, especially during 'spirited' typing situations. Anyone else feel like they can start to burn just a little bit over time? Didn't have this problem on the SP2, because of the smaller sized cover. Almost wish it had a more smooth material!
