Recommend some laptops for film editing? (Preferably not macs!)?

I got Adobe Premier elements last year but have rarely used it as it was just too demanding of my poor ageing desktop PC. For my 18th this year my parents have agreed to get me a laptop so I'm using the opportunity to get something that can edit film. Due to my program choice (and personal preferences) I'd prefer a PC, but will opt for a Mac if there genuinely is no alternative. Any ideas? thanks in advance!
