Maybe you should be asking how many people are using mobile sites ?
I only use I phone and not a desk top
For what it's worth I did and still do all my oversea ordering , international banking ,local banking , pay all my accounts & bills
Emails , Skype ,eBay ,os runways and occasionally use it as a phone , any ware , any time , Blue tooth in car & plane ,google maps, & the list goes on ,and I'm not stuck in front of a screen putting on weight !
Cheers an no offense intended .Mike
Although I wouldn't want to loose it !
