Generally speaking, any HP/Compaq system is something I would suggest avoiding. They look pretty, but are a real nightmare later on more times than not.
I don't know much about Acer to really say much one way or the other.
What I can say, is that 5400RPM drives offer little performance gain for the battery drain and extra heat they generate. Two important factors in a laptop.
And the Athlon probably would require more battery power than the Turion, but it's unlikely to be that significant. In some areas, the added performance you get from the Athlon, instead of its stripped down little brother Turion, might ultimately save battery life. Just like having a lot of RAM, which will require extra power to operate, will ultimately be considerably less than spinning up the HDD.
ok guys im thinking about buying a new laptop and im gonna buy this compaq with an 80 gb hard drive thats 5400 rpm or an acer with 120 gb 4200 rpm. both laptops have 1 gb ram, windows vista home premium. acer has amd TURION 64 X2 TL-50 1.6GHz and the compaq has AMD Athlon 64 X2 TK-53 1.7GHz. well u guys could check the techs and specs here:

So my question is which one should i buy excluding the prices? and does a 4200 rpm hd noticably slower than 5400 rpm? Also is it true that the athlon processor takes up more battery power than turion? thanx to anyone who replies.
