it IS 802.11N
i have one, got it last week. and it has an intel wi-fi link 5100 AGN adapter.
i actually DO have use for a numeric pad. it's where i put the hot keys for my DJ apps. VERY handy indeed.(i used to take a usb keyboard with my when djing for this now i don't need to!)
one of the points that i got this an insurance replacement for my (in my opinion) shitty vaio was that i could get XP drivers for it.
this is essential as the sub decks/mixer i have doesn't have vista/w7 drivers and the software is crapioca on vista and dead on w7.
thus dual booting with this is a BREEZE.
also samsung support is local to me here in Edinburgh and i know a few of the guys there. they know their stuff and are very good at what they do. i have my A+ and it's nice to speak to support dudes who are not only local but not screen reading muppets with no knowledge what so ever.
all in all a very nice laptop. would say it's a desktop replacement for my beast of a quad core with 4870 but very nice piece of kit nonetheless. i'd recommend it
