comment Laptop wireless networking options: 1x1 vs 2x2
Please tell me how type of WiFi adapter is related to antennas count? Internal (MiniPCI, MiniPCI-E) b/g adapters usually have 2 antennas connectors, sometimes - 1. Internal b/g/n - 3 antennas connectors. Occasionally n adapters comes with only two antennas. I've checked that usually best connection gives cards with 3 plugs and based on Atheros chips. P.S. +1 for good, comprehensive answer. Thanks.

@Spiff, I've checked you are right. But 802.11a isn't commonly used anyway.

comment How to determine if a 32- or 64-bit OS is suitable for a laptop based on RAM size
It is correct, but there is a little note. 32bit processors are capable of PAE feature. It means that they can address a more than 4GB memory. But you need special version of OS kernel to enable this feature. This means that you may be faced with issues (driver instability and so on). Also OS won't give to each user program more than 2-3GB memory. 64bit systems don't lack it.

32bit OS with 4GB usually shows 3.2 - 3.9GB available physical memory. Remaining memory is consumed by hardware things like BIOS, memory-mapped registers and so on.
