In search of a new Apple I found my way to the forums. I have read and read until my head is spinning. I went to the Apple store and tried to customize my order. Clicking on to what I thought was important. But to be honest I'm not sure. History: Devoted apple user. Started with the 2C, IIE, MacPlus, Performa, and now it's time to retire my iMac. Unfortunately I have never used any of my apples to their full capability and that is probably why I'm a little dense when it comes to all the extra's one can add to increase performance and get the most bang for my buck. I have a more mobile lifestyle now and need to go with a portable. I also want to learn to do more with my computer. Nothing professional but the new technology is so great with respect to music and photos and wireless I want to get on board. From reading the forums and all things "apple" it seems to me I could get a good portable for $2000, but I'm not sure where my money will be best spent. I plan on keeping this portable for some time so don't want to be wishing I had of made a better choice. (I know, I know) Anyway, I thought I'd post here since there seems to be some real experts on the subject. If I go with the 15"PB it I will not be able to do many upgrades. Maybe I won't need them. If I go with the 12 or 14" ibook, I can do more upgrades but which ones? I live in an RV so wireless is very important. I have already purchased a bluetooth phone. I'm not sure if I need Airport extreme, as my guess is, that it is mainly for networking with other computers. OK, I'll stop now and let anyone who has the time or inclination to jump in here and build me a portable for $2000.
