I think theres a lot of hype around this new version. To be honest though its more like version 6.5 then 7. Theres no major new features that many people will notice and its more like a major service pack (Like SP2 was for XP).
I suggest not to use any memory boosters. In the end they seem to do more harm then good. Just defrag your harddrive and delete some stuff from your PC (check control panel, you'll be amazed at the junk you find). Also run a spyware scan on your PC with spybot and ad-aware.
Yeah. I dumped AVG 7.5 and installed Avira. Its awesome, but it gets annoying when it tells me to upgrade everytime I update. But I can live with that.
I agree with Tarun. These programmes don't do anything. It may feel faster, but actually, it probably does more harm then good. Just use CCleaner and defraggler and your PC will run smoothly. If they don't work, then a RAM upgrade is needed.
What makes Opera so much better than firefox? Im just curious...I've only used opera once but found it daunting because everything was so much different.
