I know that at least one member has both. I had the Aspire One, and like many, got the black screen of death. (Supposedly fixed in later models) so returned it. I plan to replace it. Originally, I was planning to replace it with the 6 cell battery Aspire One. It comes with XP, but it's simple enough to simply wipe it and replace it with Fedora.
The other option I'm looking at is the EEE 901. That is about $80-$100 USD more. It's slightly more difficult get Fedora on it, but from what I've seen, still relatively simple.
The advantages it seems to have are:
802.11n wireless. (Probably not a big deal either way to me--this is a netbook, and I will probably use it for relatively simple tasks. My current home router only does b and g, and upgrading to an N will cost a minimum of around $80-$100 USD.)
Ease of upgrade. Again not that big an issue. If I get the Acer, I'll stick with the 1 Gig of RAM, which should be more than adequate for my use. (Acer has made upgrading RAM involve completel diassembling the machine, to the point of removing the rubber feet on the bottom.)
A 4 GB SSD that runs well, for the O/S and a 16 GB one that is slow, for other files.
The Acer I have in mind has a 160 gig hard drive. Again, for the use I will make of this, the difference in storage space is probably unimportant--the 8 Gig SSD that came with the first Acers was horribly slow with write speed, making an installation of Fedora with an upgrade literally take hours. I assume such an upgrade on this faster 4 gig SSD of the Asus wouldn't be anything like that. I am also guessing that upgrading to the Acer's hard drive would be more or less similar to other machines.
I don't know how much quieter the Asus SSD will be when comparied to the Acer hard drive.
One down side I have heard about, though I should be able to test this before buying as there are various stores in the area carrying the 901, is the keyboard. I don't know if the Acer keyboard is as much better than the Asus as has been claimed.
Anyway, I'm wondering about people's impressions, especially those who may have tried both. Was the quality of the ASUS generally better? Or is the higher price simply due to the name, and perhaps the N wireless card?
