I will recommend Intel in this case, as I am myself using the Turion ML-37, which I bought keeping few things in Mind,
1: I was getting better value on things that came with my laptop instead if I would have bought laptop with same configs from Dell, it would have costed me 600£ more than whaty I have paid, dell doesnt makes AMD, so Acer was choice. Turion is better in 64-Bit. better Virus protection. blah blah. bad thing about Turion is as mine is higher model, so the laptop's fan runs all the time, this many not be the case with same processor on Compaq/HP, or sowetimes i think that as I have independent 128MB graphics card, therefore it might have to run all the time to keep all things cooler. battery time even with FAN ON al the time is good at 3.5 hours.
by the time I bought mine, Intel Duo wasnt IN, else I would have went for it, the reason is Dynamic Cache (which comes in power as when needed, so as when you arent needing much cache, it draws back to RAM, and thus saving battery power required.
