netbook (bluetooth and easily upgradable)

[utherpendragon]

Looking at buying a netbook just for word processing and casual browsing of the web, although if I can watch some movies too its a definite bonus!. I would however like to use my bluetooth mouth and would rather have it internally rather than using a dongle, as well as being reasonably easy to upgrade the ram.

Are there many options available, preferably for under £250 although i can stretch a bit.

Thanks,
Rich
