Sure, but T-Mo and 3 are looking to do a real consumer push, not something that's been done to date...?
Unless it's free ( unlikely) then they'll ask for what, an extra £50 - £100 or so for it? And you still
need a USB 3G modem under contract or PAYG so in reality they're just selling an accessory that's available elsewhere, most likely cheaper and not locked to use only a Three modem.
Vodacom / Linksys routers were locked and T-mobile's Wifi only
'broadband share 100' is locked to their own dongles - it looks pretty but how would you ever unlock without f/w updates etc?..and although free on £20 pm 18 month contracts with a dongle it's allegedly £99 'offline'.
I'll be giving it a miss unless it's cheap. There's better stuff out there with built in firewalls and more functionality etc and I have too many different dongles / PCMCIA cards to tie myself in with just one type / network with an overpriced network supplied router. Some routers allow you to use mobiles over the USB connection too.
Hardly a new market segment just diversification of the current one - they still need a USB broadband dongle to use it and that segment is key.
If you already have a router and windoze computers it's fairly simple to share a USB dongle anyway....
