True, true. Downloading meaningful video streams to a cell phone with GSM or even GPRS is not going to be feasible any time soon because of bandwidth restrictions. (Although we have chalkers here, and that WiFi SD card...)
But convergence is here already, even if it's not realtime convergence. C'mon over to my house, and I'll show you how I do it on my TMobile PocketPC phone.
1) Record films/shows to PC with WinTV and SnapStream. (Alternately, download saved shows from TiVo with WinTV and WinDVR.)
2) Use SnapStream's Pocket PC converter or Windows Media Encoder to munge down the size of the file.
3a) Enable SnapStream server. Leave house.
4a) Dial into ISP from PocketPC Phone, connect to SnapStream server, and stream video files (takes a long-ass time).
3b) Save shrunken .WMV files to phone's SD expansion card.
4b) Leave house.
5) Watch whatever the hell you want wherever the hell you want to in Media Player. Yesterday, rather than leafing through germ-laden back issues of Good Housekeeping as I whiled away an hour in the doctor's waiting room, I watched "The Sopranos", while at the same time waiting on hold with the veteranarian's office.
Oh, and then at the vet's office, I read an eBook.
