The 7005 has full SDHC slot and full USB port and mini USB port I could stick portable HDD on it the full port and then use the mini with WiFi USB transmitter for say running M305 Logitech Mouse or WiFi Keyboard (this you need WiFi app) The 7015 only has mini USB it comes with the dongle.
What keyboard can I use with the 7015? I have not been able to find one with a mini usb.
