I am looking foward to a 15 inch MacBook pro with:
1. USB 3.0
2. Retina Display
3. Graphic bumps
4. Faster HDD access
5. A new design and thiness since the 2008 release
6. Mountain lion preinstalled
7. CPU bumps
8. Longer battery life
What I least look forward to:
1. Loss of the optical drive if apple can place a USB 3.0 port against its rival thunderbolt why can't they place a blu ray drive which would complement the retina display.
2. Those extra costs for going retina
Well, what I am looking forward to is a little bit different. I must say that I need/want the following features:
1. IPS Retina Display. Fonts look blurry on a Mac screen due to Quartz (compared to the crisp text on Windows due to ClearType). I can't zoom out the text I'm writing because it looks so blurry! And I also can't zoom out web pages because the elements in the page look horrible! I'm crammed inside a 1280x800 screen and I can't expand it by zooming things out! I want the sharpness that only a very high resolution display is able to provide. I don't want to see the pixels while I'm writing a text. In addition, I also want more screen space to work on, and a Retina Display is able to provide that. And I also want good viewing angles.
2. SSD. I'm so amazed by the wonders of SSD! I do have a beefy Sager laptop equipped with a mobile quad-core Sandy Bridge (Core i7), 8 GB RAM, a dedicated video card and a 500 GB HDD (hybrid with a 4 GB SSD). My sister has a 13" Asus Zenbook with a mobile dual-core low voltage Core i5 running at 1.7 GHz only, but it has a 128 GB SSD. Both run Windows 7. Although the Sager has a much faster processor and much higher specifications overall, the puny Zenbook feels much snappier due to SSD. I'm never buying a computer with a HDD again! And I don't mind if the disk space will be cut by half or even more. I can have an external HDD for backup purposes or whatever.
3. Thinner and lighter. Laptops are becoming thinner and lighter. I carry a laptop with me every day and I need it to be thin and light. And the current MacBook Pro is not. My 15" Sager laptop, which is a tribute to bad design, weighs less than a 15" MacBook Pro. Sony has managed to cram a standard-voltage Core i7 in a 13" laptop which is lighter than a 11" MacBook Air. Why can't Apple? I don't mind if the laptop will not have a dedicated video card, an Ethernet port or an optical disk drive. I know that lots of people use these features, but I don't use them anymore. It's been more than a year that I don't put a CD/DVD on a computer. I do have a top-range NVIDIA graphics card in my desktop, but for little or no use at all (I've used to pay games once, but it's been over a year that I don't; and OpenCL and other GPGPU technologies are a failure, at least so far, IMHO). I just want the laptop thin and light.
In addition, I just want it better overall. Ivy Bridge processors, of course, but that's nearly a given at this point. And bigger battery life. But not having the 3 features mentioned above is kind of a deal breaker for me. If Apple doesn't implement these in its line of mobile Macs, I'm probably giving up Macs and buying a Windows laptop which fits my expectations...
Although I think Apple is leaning towards this direction, that's still just me, my opinion and my wishes. Everybody wants something different, I realize that. Some people can't live without an Ethernet port, an optical disk drive or a large HDD. And Apple won't be able to please everyone, especially because it has only a handful of laptops and it won't expand its line. Let's just wait to see what happens!
