Why did he make a big deal on where he put the pen on the SP4? The SP2 was a magnet to the pen, the SP3 was a sticky loop, and now he said you can just put it on the side of the SP4. Isn't that no difference than my SP2? Still gonna loose if it I carried it that way. Still going to detach when I have the SP2 in a sleeve/bag.
Glad I'm not the only one! Still not an elegant solution... but I just stick it in my sleeve anyway.
