Except for the person who poorly insulted Apple.

Just trying to be informative. ^^
And for the typing issue Ctrl+Shift+left or right should do the trick.
Centrino is *not* a kind of CPU. It's a marketing term for Intel's mobile platform. It can range from a Pentium 4, Pentium M, Celeron, and I pressume Core solo/duo.
Core duo is more or less an evolution of the Pentium M. It has similar performance per clock (Mhz), and the Core duo has dual cores, and therefore performs much better for multitasking and multi-threaded applications. Pentium M and Core duo are ideal for a laptop since they offer good performance without getting as hot/using as much power as a Pentium 4 or Athlon 64. AMD's Turion competes relatively well with the Pentium M, but the Core duo is the only mobile CPU I would consider at the moment.
Different wireless technologies? I don't know a huge amount about it, but 802.11A is mostly only used in businesses and doesn't much matter these days. 802.11B is pretty much what all of them support. 802.11G is considerably faster than 802.11B and is backwards compatible. These days it shouldn't cost any extra to get at 802.11G, and it's more or less standard.
There's nowhere I can't reach.
