There are just too many threads on this
As for Ivy Bridge, if you need your MBP now, buy it; if not, wait. I got my MBP when I was well aware that there was a more superior i7 (2860QM) CPU that could go into the MBP in a silent update already, but I still got the 2.3GHz one.
Just ask yourself this:
1. Do you need it? If yes, buy. If no, continue.
2. Do you want it? HELL YEAH. Buy. If no, err, what?
That's it.
Ivy might bring a ~10% performance increase, lower heat, etc, but its mostly placebo. Hell, I've lived with a 1.8GHz Core 2 Duo for 4 years. It doesn't hurt.
As for antiglare, there are many opinions really. I personally love it, since my workstation is well illuminated (I mean, too well illuminated) and the antiglare screen can easily counter that. My glossy external monitor is impossible to read in the afternoon. So, it really helps.
If you won't take your MBP outside or you use it mostly indoors without lots of sunlight, get the Glossy.
If you want more screen real estate + above, get the Glossy high-res.
If you like that silver bezel (it actually looks more consistent for me) or use your MBP outside / take it outside frequently, get the Anti-Glare high-res.
But be warned: Fonts *are* smaller with the High-Res. Decreasing resolution IS NOT AN OPTION (it'll make things pixelated as hell), so if you don't have good eyesight or hate small fonts - get the Glossy. Your only option.
But just go in-store and check those out. I don't have good eyesight, but the small fonts were perfectly fine for me. The Glossy (Non-High Resolution) had too big fonts for me.
Just a matter of personal preference really.
