SSD is expensive and will likely be an upgradable option. Also the Intel HD 3000, according to notebookcheck.net, is as good as the (Geforce G210M) or The (ATI HD 5470) and should match the current GPU in the 13" MBP's which is the 320m.
The GPU is built into the CPU, reducing head room and probably providing a very noticeable increase in battery life. According to notebookcheck.net, old games should play well on high and new games should play well at low with this card. They were pretty impressed as this card is several times faster than the last iteration of the Intel HD series GPU.
Again, notebook check indicates this card competes on the same level as the 320m in current MBP's if not better. This is HOWEVER completely dependent on how apple uses the GPU, because the GPU has the ability to be scaled from 300mhz to 1300mhz(thats pretty damn fast).
What I do not like is the fact that those are "usb 2.0" ports. That bothers me alot considering some computers are now shipping with usb 3.0. The light peak technology by default will have a usb design, so its possible that apple could include it in the USB ports but there is no mention of that anywhere on the spec sheet that was released.
BTW, the possibilities for light peak are VERY extensive. With light peak you can have Video, Audio, and I/O action one single port because of how fast it is. They are literally using optical technology in the computer hardware, kind of like the fiber technology being used in broadband upgrades across the US.
Youtube light peak for a taste. they have been working with intel on this since 2007 if I remember right.
