Ok, so I'm new in this forum, and will be new in the mac world as well. I've been longing for MBP since I can't remember, and now the time has come to buy one. I'll buy it this weekend, though I have a few questions before I do it. Now, I know that a lot of questions are asked in this forum and most of all are by newcomers and all, and I did read a lot of them before posting this, but I don't think they relate that much, but I apologize in advance if this is annoying to frequent posters. So my questions are the following: 1) A friend of mine bought the MBP of 17'' at the beginning of the year (If I remember correctly) and I remembered that it got pretty hot after 2 hours of use probably, or more, and it was running on battery so I don't know if that's why, but , how is the heating issue on 17''mbp? Or more correctly, does the mbp overheats often? I asked this because I'm a heavy, heavy user. (As in, is ON almost all day, more than 8 hours, and all). 2) Will I regret buying it now and not wait for January? I honestly cannot wait any longer, my notebook is far to old (ok, not that old but for my needs it is) and it has only 512 megabytes of RAM. =( 3) Will I adjust to it quickly? I'm in the middle of final exams and final projects of this semester in school and I'm gonna need it a lot these days. I've read that it takes 2-3 days to adjust from pc to mac.. So , I guess that's all, I apologize if this has been asked and if this is "One of those noobie threads again", but I appreciate all the replies =) thank you.
