I don't like it. It's had a history of unaddressed vulnerabilities, admittedly it was a mere 5 out of 25 known vulnerabilities versus 25 out 75 for IE at the same time that Opera's score was zero out of zero.
The Pentagon's endorsement to use this instead of Opera as "The Safe Alternative" to IE only arose because it was less vulnerable than IE and was totally free. It seems the insignificant banner add in the free version of Opera was what disqualified it from the 'recommended' alternatives. The rest, as they say, is history.
There's also the issue of the time required for SpyBot S&D's immunisation check to deal with FF's identical immunisation requirements to IE often taking longer to perform than a scan for adware/spyware and malware crap that suggests it's rather badly written and at least as vulnerable to driveby downloads as IE (Opera is protected only to the tune of 43 bad plugins).
Also Opera is faster than IE6 which is the fastest of all the later versions of IE.
No, I've given up on that forlorn hope many years ago. My problem is that none, absolutley none of the later versions of NT were palatable replacements to make retirement of win2k a sensible option. Not even today but Linux Mint with VirtualBox looks to be about the only practical way to avoid the worse excesses of Microsoft OS developments.
It certainly does. In my case the host OS _isn't_ going to be a Microsoft product when I next upgrade the hardware beyond win2k's reach in about a year's time.
Just as you might well expect. :-)
