Hoping for the following:-
1. eSATA connector
2. enclosure redesign
3. 1680x1050 15" screen option
4. User replacable HDD (I will pop in a 320GB

)
5. ExpressCard/54 slot
(1) Hell yes! I really hope for at least that option
(2) Maybe, at least the latching mechanism. Don't give me the keyboard from the MacBook give me the latch
(3) Yes. Even though I will be eye balling that 17", it would be nice to consider the 15" just to save $300.
(4) Yes, so I can pop in the next largest 7200 rpm drives. I hope that they offer the 320 as a BTO option.
(5) FORGET IT! I hated those cards because they were so freaking slow. I miss being able to shove a Compact Flash card directly into my machine, but moving backwards isn't going to solve that. Keep the Express Card 34 slots since they are faster, but can I stick my new Apple Remote 2.0 into the empty slot so I don't loose it and always have it around?
You forgot some things:
(6) Penryn up to 2.8 GHz BTO or standard on the high end. If BTO make the 2.6 standard on the high end.
(7) Enough with the 128MB GFX RAM. Give me 256 standard and 512 high end.
(8) Can we somehow get another drive in the 17" case? Maybe a small 32GB SSD so that I can boot off of that and put everything else on the HDD. I now that the machine isn't that much bigger than the 15" to begin with but can we squeeze some more features into the body? (I can dream.)
(9) Another FW400 slot if no eSATA.
(10) Mini DVI to replace that full sized one, or HDMI
(11)New Cinema Displays to accompany the new MBPs.
That I knew about, so I guess the next question would be, how much does it cost to get it officially installed by an Apple tech or someone who's certified?
No one from Apple can do, or that's what every Apple store in the Delaware, Maryland, Virginia (Delmarva) area told me. They can only do part for part swaps and only when something is broken or wrong. You can get it done at CompUSA or any Apple Certified repair shop. I asked a store near me and they quoted me a price of about $125 --> $150 if I get the HDD myself.
