I've been all over the world, Europe, Asia, USA, etc etc...
I spent 4 weeks living in the Surfers Paradise/Gold Coast last year and decided to move here. it sunny and warm EVERYDAY, we have only had about 15-20 days of rain this year. Winter was a little cold at night and got down to about 12-15 C at night but still clear blue skys all through winter, winter only seemed to last for about 4 weeks and then its back to summer again. If you like the feel of the bigger cities then I'd suggest Brisbane, its only about 1 hour from the gold coast or other beautiful beaches.
I'm from New Zealand orginally and by christ its cold there, Aussie rocks nuh said, 45% tax rate for high earners though
that realy bites. Oh and you WON'T find a larger number of half dressed hot young girls anywhere...
Internet is fast enough, 256k upload ADSL 1.5 megabit download with 3-5 gigs a month for US$60-120.
Best country to live in the entire world (in my humble oppion) If you can get in do it
As far as hosting goes, just don't tell anyone important like the IRS what you do
Oh and yes only host in USA.
