Swung by a MS store this morning to check out the new toys. SB is cool, clipboard is very light. Unfortunately, still not powerful enough to replace my main laptop so no dice. Great solid feel though. SP4 will be a contender once the i7 version is released and thermal testing is done. Until then, not picking up an i5. But, boy oh boy, is the new SP4 Type Cover keyboard a freaking revolution!! I didn't believe it, wasn't excited about it, but figured I'd try it anyway. I was always satisfied with the SP3 version for the past year, but this new version is simply fantastic. Types and feels just like a high end laptop keyboard. Can't recommend this upgrade enough. I ended up walking out with the fingerprint version I liked the feel so much. Figured no point in investing in a new pen as I know I'll eventually pick up a SP4 in the coming months that will include one. Bottom line, go buy the new keyboard, it's that good. I take back my previous thoughts of how much better could it possibly be.
