Yo woot, what is the deal? Do you want us to stimulate the economy or what? Quit putting up this Penn and Teller's show and give me some wootoff
Think outside the box, collapse the box, and take a sharp OMG PONIES!!ing knife to it.

Does this matter?
quote from wikipedia lower # is not bad
Uses
Bluetooth is a standard and communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 1 meter, 10 meters, 100 meters) based on low-cost transceiver microchips in each device.[2] Bluetooth makes it possible for these devices to communicate with each other when they are in range. Because the devices use a radio (broadcast) communications system, they do not have to be in line of sight of each other; they can even be far apart if the transmission has sufficient power.[1]
Class Maximum Permitted Power
mW (dBm) Range
(approximate)
Class 1 100 mW (20 dBm) ~100 meters
Class 2 2.5 mW (4 dBm) ~10 meters
Class 3 1 mW (0 dBm) ~1 meter
In most cases the effective range of class 2 devices is extended if they connect to a class 1 transceiver, compared to a pure class 2 network. This is accomplished by the higher sensitivity and transmission power of Class 1 devices.
Version Data Rate
Version 1.2 1 Mbit/s
Version 2.0 + EDR 3 Mbit/s
WiMedia Alliance
(proposed) 53 - 480 Mbit/s

Two characteristics you may want to consider when purchasing a Bluetooth adaptor are its data transmission speed and its range.
The data transmission speed of a Bluetooth adaptor (a.k.a. dongle) depends on the adaptor's protocol version. The products that sell today are either Version 1.1, 1.2 or 2.0, with the last two being more dominant. Version 1.2 operates at speeds up to 0.7 Mb per second and Version 2.0 operates at speeds up to 2.1 Mbps (3x Version 1.2 speed).
Bluetooth adaptors also have a 'Class' rating which determines their range. Oldest (and now obsolete) class is 'Class 3' which had a range of 1 meter (~3.3ft). Today you can find products that are either 'Class 2' or 'Class 1'. Class 2 Bluetooth devices transmit up to a range of 10 meters (~33ft), while Class 1 devices transmit up to 100 meters (~330ft). Classes are not version specific; older Version 1.2 adaptors are Class 2, more recent 1.2 and 2.0 Versions are Class 1.
An important thing to keep in mind when buying a Bluetooth adaptor is that neither the connection speed nor the range of your network will fully be determined by your adaptor. After all, it's a network and the receiving device also has a thing to say (bottleneck issue). A Class 1 , Version 2.0 dongle, for example, will not perform up to its maximum range (330 ft) or maximum data transfer rate (2.1Mbps) if it is paired with a receiver device (headset, printer etc..), that is Class 2 and that is Version 1.2. The speed and range of such a network will be closer to the inferior values in each category, in this case closer to those of Version 1.2 and Class 2. However such a network should still work fine because the version and class protocols are backward compatible; units with newer protocols will work with units with older protocols.
To sum up, buying the adaptor with the best features will not necessarily make your Bluetooth network faster or further reaching unless it is paired with a receiver device that is equally advanced. Today, for example, almost all Bluetooth headsets you can find in the market are Class 2 (for practical power saving purposes, since these devices need regular charging) and hence will not work at distances much more than 33ft even if they are paired with Class 1 adaptors.
Thanks for the story. So do I buy this or not?
Programming today is a race between software engineers striving to build bigger and better genius-proof programs, and the universe trying to produce bigger and better idiots. So far, the universe is winning.

Is there any truth that these dongles (and others mass-produced in Asia) come pre-loaded with trojans and other harmful malware? And these aforementioned programs cannot be removed from the boot sector?
