USB key with bigger antenna to improve wi-fi reception?

As a way to improve reception to the occasional weak public wifi hotspot, I'm thinking of switching from the 802.b/g/n wifi connector embedded in my laptop to a USB connector with a big antenna like the TrendNet TEW-645UB or the Belkin N Wireless USB Adapter.

"that it does improve wifi connections
enough to make this purchase
worthwhile

Simply put, yes it does - BUT it depends heavily on the type of chipset you are using, and the strength of the antenna. Plus (and don't get me wrong) you can buy them cheaper then the ones you highlited.
I would recommend an usb card with rt73 chipset and antenna plug, and a 10dBi antenna, and you can buy both for max 40 - 50 bucks.

Whichever your choice is, always take into account the strength of the antenna in dBi, and note if it's a omni-directional or directional antenna. Note -- 10 dBi antenna is approx 40 cm high (1 ft. 3 in.), so passers by could give you a funny look =)"
