Just a few points:
On PAYG, cost per MB is same for 3G or GPRS (on Voda).
The Optima card doesn't do fax.
Yes wifi is much better and - unless you are after just a few TAFs etc - cheaper, but getting it
when you really need it is something else. In the context of flight planning one really needs it in one's hotel, and most motel-priced places don't offer it.
Disable auto update of antivirus/etc software and Windoze itself, otherwise you get big bills.
Voda customer service is quite amazing. Never knew one could assemble so many useless thick stupid unhelpful disorganised people in one place, with so little collective IQ. A tribute to modern-day HR. However, they have a "Directors' complaints" department - basically if you complain to one of the Directors (by name) it goes to this dept and they are in a different class. I had the phone # for it but have lost it.
I'd like to know what the monthly payments are on a GPRS tariff which gives you 450MB free data per month
And I won't ask what "material" he was downloading for the £2k
