I don't understand all of the criticism regarding the Acer One.
I run windows Vista on mine (which is generally considered to be a pig of an OS) and, with most of the cumbersome settings turned off, it runs perfectly fine.
In fact, I now use my Aspire One as my main computer and have passed my MacBook Pro (Seceond Gen) on to my daughter.
I use office, firefox, have thunderbird constantly running, edit photo's, some activities of a dubious legality (utilising TPB) and have no problems playing older games like baldurs gate.
Also, the wireless on this is pretty savage and finds wireless connections beyond the range fo my girlfriends PB Laptop and my daughters MacBook Pro. Incidently the MacBook Pro has intermittent connection problems with our BT HomeHub and my girlfriends PB Latptop won't resume wireless after sleeping. My acer one has none of these problems.
You can swap the HD for a larger one, 1.5 GB ram is plenty for a lot of tasks, the camera is fine, the screen is really clear (in all light sources I have tried) and the connectivity, as noted, is spot on.
The only complaint I have is regarding the speakers, which are absolute crap. But I can live without these.
I also quite like that the external DVD burner I bought, for occasinal use, is twice the size and weight of the laptop.
I would like to try Win7 on it, but since there are no problems so far I'll leave it as is.
I have been playing with, building, breaking and fixing computers for the last en years. This laptop is the only computer I have had that has lasted over three months without needing the OS re-installed.
