Check out some of the imports from dealextreme...
Most of these, as of last year, are using the same chipsets. Depending on what pins the mfg decides to connect hey can get usb , hard disk, memoy .. etc etc etc. but basically they all have the same limtation in features dependant on the chipset.
There are only about three or two chipsets that are used in everytihng from Zune to Ipods. The technical specs therefore are also very nearly identical..
The only major differences are color, the molding of the plastic case (in some but not all cases) , and that's about it.
When these things are made in China... the plans for the device goes in the front door when it's designed in America, and goes out the back door when it gets to the plant. then it goes a mile down the road to another plant and the same kind of product is made with the same basic plans... minus American taxes, minus marketing fees, minus legal and lawyer fees, minus worker (in usa) compensation and health care, minus OSHA rules costs (in the USA) .. so you get basically the same product for 1/4 the price.
By the way, why do you think gold is so high right now ? The US Dollar has lost nearly 1/2 of its buying power compared to the Euro since the Euro came out in 2001 (about) Remember when it was 2 Euro to 1 dollar ? It's now 2 dollars to 1 Euro (about).
Save your money... buying now is a fools game.. invest. At least invest in yourself. If you're going to buy something.. take it apart , learn how it works, and get an education and a better job. Forget about buying MSoft crap.
