MTK2 usb GPS's?

[Wolfgang S. Rupprecht]

It has been a while since I made the rounds looking at the state of the
art GPS chips. At first glance, it looks like the MTK2 might be the
most interesting chip out there in terms of sensitivity and the spare
CPU time to track a large number of GPS satellites. While I have been
able to find a large number of google hits for folks getting excited
about this chip, I can't find all that many GPS's that actually use it.

What is up with that? Is the chip still in the glossyware stage? I'm
really interested in finding a USB "mouse" or usb "thumbdrive" style gps
with the MTK2. Are there any available yet?

You could always send a query direct to MediaTek's marketing

Another user of the MT 3329 (although MediaTek's web site shows only
MT 3328 under Navigation Products):

More GlobalTop products, some of which use this chipset:

MediaTek mentions of MT 3328, MT 3329:

Thanks for the links Ed. It looks like in practice there might not be
that much (if any) advantage of the MTK over the SiRF-III.
