I'm pretty much settled on buying a ST5022, the only thing I don't have answered yet is to get the 5022 or the 5022D. It seems the only diff Centrino b&g; vs the Atheros Super AG. I'm using a standard Linksys wireless G router at home. I don't know much about the Atheros. Any insight as to why I should choose one over the other? I'm not a very "technical" person.

My Tablet PCs: T4010 |

I personally went with the T4010 over the T4010D because it had the centrino. Based on what I've read, the centrino uses circuitry that's already integrated with the Intel motherboard chipset and CPU, therefore theoretically (hypothetically) using less power - although the Atheros is called "integrated" as well.
Some other things:
* centrino drivers are no available for linux (as are atheros)
* centrino has been praised for good signal strength
* Atheros has 802.11A compatibility, though I never see any networking device support for it (Airport extreme and Linksys for example use G/B) which centrino supports
* centrino should in theory be more power effecient
I suppose I went with the path of lease resistance. Hope this helps. |

Not really. "Centrino" is simply a marketing term devised by Intel to identify a specific subset/grouping of Intel products for the laptop's basic chipset, the processor and the WiFi card--three that Intel has "certified" to work together efficiently. They haven't yet certified an a/b/g wifi card hence the builders can't put the Centrino logo on the tablet if they put ANY "a" wifi in it--even if the Atheros card used LESS power (I don't know if it does or doesn't). |

| Right, it's not "integrated" any more than the Atheros. It's just the Intel PRO/Wireless 2100 card as opposed to the Atheros card. |

| Thanks to both of you. Being that I'm not aware of any "a" networks that I would encounter, it sounds like the Centrino will satisfy my needs. I just didn't know if I was giving up anything by going one direction or the other. |

dchuck, You're quite welcome. If anyone has anything else to add about the Atheros vs. Centrino wireless issue, please add. Non-anecdotal evidence especially welcomed!
Atheros has a marketing paper called "Centrino vs. Pentium M: The Battle for Wireless Notebooks" (http://www.atheros.com/pt/Centrino_vs_Pentium_whitepaper.pdf) that claims Atheros is more power effecient by sending data faster. Now, I take this with a major grain of salt because I belive they're talking about their "G" implementation, and not everyone even has "G" access. Most public access points for example are "B". There's also supposed to be a lot of issues with "G" interference. Anyway, I'm still happy with my centrino choice. I'm sure Atheros is a worthy product, but I don't think it's a clear winner until someone gives me some hard evidence :) |

| Centrino and Atheros are integraded to mini-PCI of the motherboard. I'm currently using Atheros a/b/g on Fujitsu S series, and my brother have Centrino version of Fujitsu S series. Mine(atheros) have longer range and better signal than my brother's centrino laptop. But it is possible because of my router (netgear fwg114p) is using atheros chipset too, result in better signal and better range for my laptop. This is just my opinion. |

| Thanks rz... I am thinking maybe the Atheros would have been a safe bet, but I'm still content to get the centrino card. Definitely not going to be worth an upgrade unless I have really awful signal. |

sshear, thanks for the update. I previously pointed that out on another topic (I found the information on the Kismet web site), but when I first posted the topic I hadn't yet found it.
Have you used a centrino under linux by any chance? What was your experience like? |

One thing that leaned me toward Atheros is the 802.11a, I have wireless video and cameras that run over 2.4 and the microwave that causes me problems with 2.4 I haven't bought my new A/G router yet, just using 11b.
