I would steer clear of the Acer TBH mate.
I have an IBM T60 (Thanks to my co), and my sister has an Acer.... The Acer makes me want to cry every time I use it... It's creaky, flimsy, runs hot and noisy, and the whole thing just feels poor quality.
The IBM is much more solid, has metal hinges, better screen, better keyboard, and does not creak at all- how a laptop should be! The comparison is like night and day...
Not saying you should go for an IBM, as they are very work- orientated machines, but avoid Acer at all costs in my experience!
