Howdy Bird,
Almost everyone with a keyboard & monitor will "give" you advice. In my opinion, Dell is the best choice for buying a computer today. They supply the best components, usually are first with new technologies for the desktop market, and their service is superb (I speak from experience here).
One thing about Dell is, though, that if you ordered from their "home user" section of the Dell web site, you were probably charged $300+- more for whatever you bought. You likely could buy the exact same machine and configuration via their "small business" section of the web site for considerably less. I suppose they justify this "dynamic" pricing differential by the fact that most home users will require considerably more support. But, if one has a choice, order online by selecting the "small business" button, and pay with a credit card. You'll save a little.
You will in all liklihood notice a significant increase in speed from a 3 year old IBM to your new Dell machine.
Also, satellite wireless broadband "should" be becoming available even in regions like yours (and mine), fairly soon (maybe by the end of the year???).
Anyway, congratulations on your new machine. You done good. Enjoy it.
