IS THERE A TV TUNER FOR A LAPTOP THAT DOES NOT INVOLVE CONNECTING UP TO LOCAL CABLE?

for wireless internet, you need a wireless broadband modem, or to connect a mobile phone to your laptop

for tv, you need a tv card in your laptop (or USB tv tuner) and an aerial to recieve the signa, but make sure it’s digital tv otherwise you’ll need a very large antenna

and wireless cards are very available. i bought a digital one from ebay for less than $50 AUD about 3 months ago

and the first answer was also wrong, as wireless network cards only allow you to have wireless internet 30m (max) from your wireless router. (which may be all the mobility you want)

there are plenty of wireless boradband plans available, but tehy are very bad value compared to normal broadband however you can connect to the internet almost anywhere.
