Just taken ownership of an Acer Aspire D250-1838 and it seems to be a great little 10" unit.
Windows 7 starter doesn't seem to be missing anything I need and runs well with the standard 1GB of RAM.
Wifi is 802.11b/g/Draft-N, HD is 250GB.
Battery life is claimed to be 8 or 9 hours.
Webcam has very good resolution using Skype.
At US$365 on Amazon, I think it was a bargain.
