Having lugged laptop bricks on and off planes and trains, my shoulder cried out for something that would be portable in a non-ironic, non-muscular straining sense.
I bought the Linux version of the Acer Aspire intially, and whilst a brilliant inexpensive machine, the operating system didn't have driver for the built-in microphone, so my aim of recording meetings with it and the built in webcam were impossible. But I returned it to Amazon with no fuss, and upgraded to this Windows XP version.
It is so light and highly connectable. I use it in meetings, on business trips, to run presentations, work in free wifi cafes, and sit in my reclining chair catching up with blogs.
I use OpenOffice, Firefox and FreeMind map minding, all open source software. Whilst I enjoyed the challenge of Linux, it easier to use XP if you have any experience of it.
My only problem is that it is so cool and dinky, especially in the extra red leather case I bought for it, my partner likes to take it when she goes to see clients, and catch-up in cafes. So the only conflicts I've had are whether it is mine, hers, or ours.
It is very liberating to have something you can pop into your rucksack and forget about, till you need a fully featured computer.
