OK, diapered prodigies, I'm tired of IE9 puking on me. I'm aware of Firefox and Chrome as alternates. Tell me why (or why not....) I should choose one or the other. Feel free to throw in other viable options if any.
I've got a 3 yr old Compaq with 7550 dual core processor and Vista Home Premium
No, I'm not interested in ante'ing up cash for another operating system. If it came to that, I'd buy a new 'puter and turn this one into a UNIX machine for experimental/learning purposes.
Also, if it makes any difference, I'm using some version of McAfee I get free from my ISP. As you've no doubt figured out from posts on other topics, cheap is my middle name.
