Flurry of posts tonight. Sorry. I'm addicted to the new toy. I managed to stretch to the 256Gb MBA but even then I have concerns about disk space, in particular as I'll probably partition off 70-100gb for Windows 7. I was thinking on what the most inconspicuous solution would be to expand the storage and I thought either a usb 3 flash drive (ideally v small stub) or a SDXC card. Is they viable options or just too slow? Are there other alternatives? My issue with an external drive is that it's a bit unwieldy having a drive with a short cable sat at the side when I use the device on my lap etc. Interested to know what everyone else has done. Thanks Richard.
