Good idea DN, but I'm just wondering if there would be any noticeable advantage to transmission compression on a PC connected to a decent broadband service? IIRC data compression used to be offered at the ISP's server when dial-up was prevalent. Since mobile phone data transmission is likely to be way slower than a DSL/cable PC connection - especially if EDGE is used - compression may still make a difference there.
Anyway I just tried Opera on the 3GS and it's extremely fast at loading the full web pages; much more than the version of Safari. However the landscape rotation is flaky (doesn't auto-widen), and the pinch-magnify only works on one big step! Text isn't rendered that brilliantly either
