If that handy SD slot in your Treo (or similar smartphone) has gone lonely long enough, you've probably been waiting for "that killer device" to slam down in there and boast about. Thankfully, that time has seemingly come, as Spectec's latest SDIO GPS receiver packs a whole lot of functionality into a minuscule (and sleek) package. Unlike alternative GPS attachments for your handset, the SDG-810 provides a SiRF Star III 20-channel tracking adornment, is WASS-enabled, and sports a microSD slot to carry up to 2GB of excess data (like maps, for instance) since your original flash memory slot just got occupied. While pricing information wasn't readily available, this nifty smartphone must-have should be available in your neck of the woods (read: everywhere) real soon.

Engadget Mobileに台湾のSpectec社からSDIOでSiRF Star IIIのチップセットを採用したGPSアンテナにmicroSDスロットを搭載したカードの生産が始まるという記事が掲載されています!
iPAQ rx4240や既存のSDスロット搭載のPDAなんかで使うとGPSアンテナと地図を入れられるmicroSDスロットがあって便利かも知れませんね?(^^ゞ
