The first is the Gateway LT3105/LT3106 here:
Athlon 64 is quite a bit faster than the Atom, decentish battery life (5 hours), light (1.2kg). But also has no 3G, and no 802.11n
The other contender is the HP 5101:
Unfortunately I cannot find one with a 6 cell battery (9 hour), they all come with 4 cell (3.5-4 hour). And integrated 3G seems to add quite a bit to the price for something which will only be used if we go away for weekends.
I might be overlooking something. For what it's worth she's vetoed the Asus EeePCs as being 'ugly' and complaining about their trackpads. Otherwise they're certainly specced the best for the money.
