But the universal service subsidy is in a different pot than the cell phone subsidy, right? btw, when I washed my old Motorola V195s quad-band GSM cell phone, I replaced it with a $5 cell phone AT&T was celling for prepaid service. AT&T gave me the unlock code. I'd prepaid for a minimum number of minutes, but it turned out I didn't even need to do that. I've been using it temporarily, but I haven't bothered shopping for a better phone. I won't care if I drown this one. I don't see how the government subsidy can make cell phones any more available. Anyone can afford a $5 phone without a government program.

Even the original HP PrinterPal devices had failings you may not recall: according to the HP page http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=&docname=bpf01315&lc=en&product=58855 : The HP PrinterPal (C2970A) is compatible with the following HP Deskjet printers: : HP Deskjet 500, 500C, 520, 540, 550C, 560C, 600, 600C, 660C, and 660Cse printers. : : The HP PrinterPal (C2971A) is compatible with the following HP LaserJet, Deskjet, and : other printers: HP LaserJet III, IIID, IIIP, 4L, 4ML, 4P, 4MP, 4, 4M, 4 Plus, 4M Plus, 5P, 5MP, : 5L, 5L FS printers, HP Deskjet 310, 320, 340, 850C, 855C, 1200C, 1600C, 1600CM printers, : HP Copyjet Printer/Copier. : : NOTE: ... The HP PrinterPal is not compatible with any Macintosh-only printers, : such as HP Deskwriter printers or PostScript (R)-only printers. Not USB, but actual "HP PrinterPal" devices are still available, at prices ranging, seemingly, from $60.- to $280.- and up, from various resellers, according to the very frugal froogle.google.com purchasing-search site.

Cheaper to buy a 'real' fax machine, or o 'all in one". Every "all-in-one" I've seen, including the one I use today, is really a "not-quite-all-in-one". The gadget can take documents from the PC and print them or fax them someplace; it can copy a paper document; or it can send or receive a fax to/from a paper document. It can even scan a paper document and send it to the PC. But it canNOT receive a fax and send the result to the PC. I have to receive the incoming fax as a paper document, then scan it in manually before the PC will accept it. Why are there no true All-in-Ones?

Great if you can get cell service. That would make sense only if the USF is going to pay to extend cell coverage to the many places that don't have any (including a few where local politicians have made the decision not to allow it). How likely is that? And will it address areas that have some but not all of CDMA/TDMA/GSM coverage?

Several visits from "crews" composed of accountants, marketing guys and managers failed to solve the problem. Finally, one manager type went tearing off in the truck to the big cabinet 5 miles away on the main road. Claimed to have yanked out a circuit board and stuck in a new one. The hum was gone. Off they go, happy and proud of theirselfs. Only now our dial phones no longer work. Oy. Well, I'd been collecting up Nortel 2500 sets from junk stores for a few years so we just swapped a couple of them in and all was well. Returned two 500-type phones to Aliant. Our bill went down. No new charge for "touch-tone" but no longer rental for the dial sets. -- Mike Spencer Nova Scotia, Canada Clinging robustly to the trailing edge of technology.
