Barry the N270 is 32bit, you will be able to get Linix Lite to run on it as I did it for someone last week at work on an old Acer One (older than yours and less powerful). Being 32bit you will need to go for an older version. Its straight forward to install but bear in mind I did it on a notebook with keyboard and trackpad not a tablet.
On some of the old netbooks it had a lite version of windows which you cannot get hold of so if hard drive goes the netbook is scrap in effect so Linux is a good option. I did manage to get windows on one as I had Action Pack disk with the right version but was not a straight forward job. I think these may have been limited to early netbooks though but if you run Linux as a Live disk first (which Linix Lite does) you will see if it is okay before going for the install and possibly losing windows.
