Reply to About to buy S4, but worried about laptop spec.

Hi all, I'm about to buy an S4 (and pretty excited about it!), but I'm worried that my laptop might be a bit slow. It's a HP Compaq nx6325, AMD Sepron 3400+ 1.79 GHz and 2.37 GB Ram.
Its running XP Pro SP3, which seems stable to me.

I know this is less than the recommended specs, but I'm running TPro now with no problems and am hoping someone can reassure me so I dont have to shell out for a new laptop.

Any advice would be much appreicated.
