For what it's worth, there's a very decent Plex client that is under active development (check the plex forum). This app is why I went with smart tv. All the perks of plex/xbmc without another bloody roku/htpc box to drive it.
With only 47 participants this study has, in my eyes, about the same validity as the average undergrad study.
I'd love to know what kind of experimental psychology you do that typically runs so many hundreds of participants that you see 47 subjects as equivalent to an undergrad project.
I recently bought a used Droid 1 on ebay for cheap. Switched from Verizon to Page Plus (prepaid and no data plan) and am saving buckets of money compared to my dumbphone plan and since I'm always in WiFi for 90% of the time I get to have all the perks of a smartphone. Easy e-mail checks in meetings, apps for scouring forums,web browsing on the go to check movie times or what have you, etc.
My droid has replaced my GPS (maps downloaded to SD, don't need data plan for this) and my expensive MP3 playing alarm clock (Droid in a media dock = success). Smartphones don't have to be expensive, the Droid 1 is plenty fast. Faster if rooted and overclocked. If you got good wifi coverage then you don't need an expensive data plan. After flipping the dumbphone, GPS and alarm clock on ebay, I made money on the switch.
This would have been obvious if you had read the article. No guilty knowledge for you!
