Second that. For a laptop you'll pay at least 20%-40% more in Doha. Ripoff wherever you turn.
In the last 3 years i bought 2 laptops for myself and 2 for my gf, always online, with s&h it was still much cheaper than here. Saved probably $1000.
You might have problems with your warranty... Still I think it was worth it, I haven't seen a good laptop service center in Doha yet. :(
