Been hanging out here for around a month now awaiting the upgrade and now that it appears that my wife has finally agreed to it, I am finding myself torn. Here has been my thought process: 1. Prior to the update, there was absolutely zero question that I would spring for the 13" 2. Then they kept the C2D. I am not hung up on specs, but I want something with staying power for technologies we cannot yet see. Now I am doing something I hadn't thought possible: looking at the base 15". I will admit that my opinions have been influenced by what those on this board have been saying regarding screen real estate, dedicated graphics, processor that can never be upgraded, etc. I do not, however have the $ (well, I'm not willing to spend it) on an upgrade to a hi res screen, and I don't particularly think I need it either. 3. Now that I am torn, here is what I will use it for, in order of most use to least use (from what I can see) surfing/blogging email iPhoto iMovie PS CS 4 only very minor gaming, and that would likely be done by my wife (facebook games, etc) 4. Considerations that I am juggling: Portability (I have a 24" early 08 iMac that I can never get on because my wife is always on it.) This includes battery life and size 5. Performance/Staying power. While CS work and iMovie stuff is near the bottom of my list, I am hoping that with a portable machine, I can do more of this stuff on the couch whilst spending time with the fam. (The rest of my family lives 2300 miles away and I like making movies of my son for them and sending them pictures) My first consideration always takes me in the direction of the base 13" (which I would upgrade eventually with a SSD as prices come down) based upon battery life and size. I am also slightly inclined in this direction due to the fact that I am not hung up on specs necessarily. From experience, when I purchased my iMac, there was a wait for a pending upgrade and I finally decided not to upgrade (and got my first Mac) I can honestly say that I have never looked back, even with the subsequent upgrades to the larger screens and better specs, etc. It is still a superb machine @ 2.5 years old and feels brand new to me. I can see using it for 5 more years. My second consideration always takes me in the direction of the 15", due to having some additional screen size for video and photo editing, along with misc multitasking. Also, now that I actually waited around for an upgrade this time, I want to get the most staying power out of my machine. I think the base 15" is a great looking computer for that. I do have a concern about a feature that is supposed to be great, but is detrimental to battery life. Auto Graphics switching. I'll not approach the need for 6 or more hrs of battery life on my comp 98% of the time. But I'd like to be able to use it for on-the-fly movie creating while on vacations (including planes) and I don't want to be tied to an outlet (as I currently am with every other machine I have used), including my iPhone. (BTW, I am a bit hung up on specs with the iPhone and do just have a 3G but cannot wait for the new one this June!!) So there it is, any suggestions?
