Desktop PC vs Laptop

As my laptop is nearly completely broken now I was thinking about getting a new one but I not a very computer technical person so maybe you guys can help. Most laptops I look at seem to be better than the desktop pc's so are laptops better now. I have a budget of about £200-400 to spend on my new computer. It would be maily used for internet, photoshop, schoolwork etc so that dosen't take alot of money but for £400 would it be possilble to get a PC that I don't have to build myself to play a few games like Spore, Viva Pinata and football manager 2009 without any lag. If I can't then I'll just get a cheaper system in the £200-£300 range and buy an xbox 360 again.

Thanks for any help.

For the usage pattern you listed a laptop should do you just fine. Make sure it has got either an nVidia or ATi chip in it though and not just the Intel integrated one.tautitan123
