At least if we could buy the used ones that will appear on eBay...
We do have AWS in Brazil now, though.
Brazil really needs centralized sites (Amazon, CL, etc) because having to check dozens of sites and services just to maybe find something similar to what you need, it can get tedious...and I'm sure I'm not the only one. At least there's Estante Virtual for used books. That's a great service.
As long as we're on the subject, it'd be really nice if there was a way for non-Brazilians to buy things online here. This would be solved if PayPal upped their marketing and really made themselves known on the Brazilian market.
Estante Virtual is really great - the moment I found out about them I stopped going downtown to hunt for books (the good thing is that they're just "forcing" owners to index their collections, and they get to be the middle man).
Dell is established, affordable, good customer service. Competes here with Acer, HP, Toshiba and even cheaper brands probably assembled in Brazil (like Positivo). Sony Vaios are normally a little bit higher priced, closer to Apple.
The lower end Dells start around R$ 1700 (820 USD): Core i5, 4GB Ram and 1 TB HD. The higher end (gaming or slim) ones, my guess would probably be around R$ 3500 (1700 USD).
Now, what were you saying about being ripped off?
[edit] just for kicks I maxed out a Mac Pro: R$ 48.959,00, or 1/4 of a nice brand-new apartment.
