Finally my office will buy me a new laptop, I asked for a Dell XPS I5 with 1 GB Nvidia Graphics BUT due to some obscure rules I can't order by mail so I'm forced to buy local.
There's not much to choose, I saw 2 HP laptops, both has 4 GB memory, 640 GB HD, Led screen 14.5"
Differences:
DV5-2237 AMD Vision Ultimate Processor (AMD Phenom II 4 cores) Radeon HD 4250 Graphics (it has 128 MB dedicated memory) , Blu Ray + DVD (in Spanish)

This computer will be with me several years so any comment that leads to a good buy will be welcome
