6400 is the model sold in Canada and in the US business section of Dell.
E1505 is sold in the US home and Home businesses section.
I own this model. Very ncie laptop.
You can get XP in option when you choose it from the business section.
Vista is nice. Simetimes unstable, but we must give him a chance : as you said in your post, it is a new software. Having XP and Vista in dual-boot is the best actual option. XP is stable and fast, Vista is beautiful but a little bit unstable.
It is possible to install Vista later when you have XP. You can install it in dual-boot. I have a dual-boot with XP and Vista.
Upgrading in Vista isn't a priority since softwares are just beginning to be compatible with Vista. Maybe at the end of the year Vista will be a lot more popular.
Make sure to get an ATi Mobility Radeon X1400 if you want to have the best gaming potential. If you want to stay with the GMA950 ( if you want to get more battery life, this is the choice to make ), you should go with the E1405. Less heavy, easier to manipulate and carry, it is a nice computer.
I posted a while ago of my interest of a Dell 1705 and thank you for your replies. But now I have another question upon the Dell inspirion 6400 and 1505.
Now I hear that they are basically the same, but what are the differences exactly? I went to the Dell home page and tried to see but they both have similar options except the 6400 has a XP option.
I see from other forums and reviews that the new Window Vista is kind of on the fritz right now and still has bugs because of being so new right now.
So I was thinking about getting a 6400 with the 2.0ghz options and all the top notch stuff added(it came out to about less than $1400)but with an XP OS.
Is this a good idea to do than to get the new windows vista?
Is it possible to add windows vista to it manually with a cd later on?
Is upgrading to the Vista OS a priority in this year?
please reply back... I don't wanna just blow $1400
