I know what you're talking about there with server os'es. It's more than just the memory. The cpu and memory will be able to pass around chunks of data twice the size at the same speed compared to 32 bit stuff. That just means more throughput.
I've moved over to 64 bit fine. Stuff like video processing software does run much faster in 64 bit. The most i've done with that is convert xvid videos to dvd playable format, and instead of an hour and a half, it got shrunk down to 20 mins. It was pretty nice. 64 bit does mean extra speed for whatever software was designed to take advantage of it. The odd fact that second generation netbooks don't have 64 bit capability by now is just odd. Like i said, intel atom processors have 64 bit capability except for the N and Z series. Methinks this is what will make 32 bit not die anytime soon. I'd just prefer to run 64 bit. I'll have to bite the bullet on this one. It's still a good buy, the asus eee 901 will run all of my favorite foss games like openarena (not going to play fs2 open on it).
My brother did recommend getting a nokia N810. But, that didn't sound like it was for me. Netbooks can do more than just surf the net, they can play older games relatively great, great battery life, good hardware compatibility with windows and linux, not to mention it's a complete package...camera, microphone, extra usb's, two good os'es to choose from, etc. Basically it will do more than just surf the net. Me and my friends gather together frequently to do lan gaming with only fos games. Assault cube, openarena, and urban terror. The fact that i can play these games on the eee 901 is fantastic. I'll mainly be using it for it's portability and battery life with general use on web surfing and typing. The SSD guarantees i wont destroy the laptop hard drive when spring hits and i'll soley be riding my bike to classes. Linux compatibility should i stick with xandros or plop something else linux on there will let me use 32 bit apps well into the future and guarantee linux compatibility with more than just hardware. I'm a big fan of linux software, and a device with all hardware compatible with linux is really great for me. Also it doesn't weigh that much and is very small sized. I wont need to buy a special laptop case for it at all. I'll just shove the eee 901 inside it's protective sleeve it comes with and put it in my backpack. Porting around my backpack with main laptop i never like doing.
Also, for the value of my laptop, i realized i could get a netbook and a no os desktop gaming machine for the same price. Idk if any of you wants to buy a vostro 1500 for 500$ bought mid summer 2008 for $500? 1.4 core 2 duo, dual channeled 2gb memory, 8400m gs 128mb, dvd+-rw burner, 120gb hdd, 15.xx inch laptop capable of 1280x800 max resolution, intel pro wireless b/g. It will play ut3 and fear 2 demo. All of the hardware is linux compatible, and not even necessary to go to dell's website for driver hunting...vista detected and installed everything fantastically with no driver hunting needed (even better since dell didn't release 64 bit drivers for vista for this model...talk about getting lucky...i was messing around with vista and found out some great new user habits for windows users...UAC IS GREAT!!!).
