Ken, the Aspire One works for me.
Trackpad: I've never liked the pads on ANY laptop I've owned. I use a very small USB mouse.
I wouldn't say battery life is a plus (~2 hrs), but then I don't think the original battery is good on any netbook. I'm probably going to spring for a bigger battery. But I usually use mine mostly in my room at night, wall-powered, when I have Wifi access, so battery life generally isn't a problem. It would be nice, however, to use it for longer on the flight over and back.
The display is fine. I'd prefer a full height, but that's what you give up for the small size.
The keyboard is a little tight, but I have thin fingers. I still have to look at the keyboard now and then to make sure I'm in the right place. It's still better than using a local cafe keyboard.
Software: I think it came with a demo of Office 2006(?). The last good version of Office was 2000. That's what I use. I just transferred it from my old notebook. Other than Word for a journal and Exel for schedules and expense reports, I don't need much. My camera came with all the photo editing software I need, and I use Notepad for my website files. Oh, yes; it comes with Internet Explorer, which is important.
Partitioned HD: You would have to mention that! Yes it comes partitioned - the first partition is the recovery stuff, instead of a recovery CD. After that it is just one huge partition. I like to put data in a separate partition from the system/software stuff to facillitate backup. I have partitioning and backup software, but I still haven't figured out for sure how to go about it without losing the recovery partition. But, I don't store a lot of stuff on my computer, and it does have an SD card slot (in addition to a combined MS, SD, etc slot), so I just got a card, and I put all my data there. It's nice, because I can take the card out and put it in my desktop before and after the trip.
