Hey everyone, my question is anything but new...still, after reading a lot of threads in this forum I couldn't make up my mind. The point is that I'm searching for a new computer, which I'm gonna use primarily for statistical modelling, intensive spreadsheet compiling and processing in MS Excel (with more than 500,000 rows) as well as occasional running of MS Access for database management. Would I be better off with a new iMac i7 or a standard i7 PC (let's say Vostro 470 from Dell)? I fully realize that I can run Windows on a Mac to utilize MS Office, which is (as far as I understood from this forum) much more efficient when being run on Windows rather than OSX. But what is the point of buying an iMac if I have to start Windows every time? Of couse, with an iMac I'll get a brilliant screen with keyboard and mouse included, but still, I can order an IPS monitor from Dell + keyboard + mouse + PC itself for the price, which is twice as cheap as Apple's iMac. Nonetheless, something, which still makes me hesitant, is the outstanding design of iMac...it's simply amazing, although one has to sacrifice the ability to change any hardware after the purchase (except for RAM, of course), which is not the case with a standard PC. So, I would be really greatful if anybody can help me out of this terrible dilemma.
