Have I done something I’d regret someday?

Last week, I finally did it. After more than a month of contemplating, I finally had my Acer laptop downgraded from Vista to XP, so I can use it with HSDPA. (Yes, this kind of things needs serious contemplation.)

A good friend of mine helped me with the downgrade (should it really be considered as a “downgrade”?) but he had quite a hard time finding the right drivers and stuff. He was successful nevertheless. See? I’m not really a geek. If I was, I wouldn’t need another geek’s help when it comes to stuff like this.

Anyway, so far,Ice is working fine but once in a while, I feel like the system’s slowing down or something. Sometimes I have to reboot to make it run faster. (Or am I just paranoid?)

What are the downsides of downgrading a Vista-enabled laptop to XP? Will I lose my warranty? (Gaah I didn’t bother reading the contracts and all haha.)
