Hello all, First post here after spending the better part of my afternoon lurking. I am a after a longwhile of telling my self I never would, finally considering a mac. This is after spending a good deal of time with Windows Machines: I have a Thinkpad running Win7 and a 12" netbook running Windows 7. I take pretty good care of my machines but they have recently had me at the end of my line in terms of how they are annoying the hell out of me: Random freezing, restarts, sometimes gets frozen at the BIOS boot screen. Not sure what's going on..there. I was also fortunate enough to get a CR-48 from google (typing on it right now). It's nice but not up to the floggings I like to give my computers performance wise (have 40 tabs open and stream HD video). I will be starting graduate school soon and the calling card of academia is a Mac so I'm looking to cross to the dark side and get one. Was posting here to see if you all could advise me if a mac is right for me and what model is best. The tasks I do regularly is using Mathematica and puTTy to do modeling for chemistry. I do a lot of internet browsing and routinely have 40+ tabs open. When I am in work mode I have 40 tabs open (streaming Pandora, couple HD youtube vids), 4-5 excel windows, 1-2 word windows, while I'm downloading stuff via torrent (we share large cluster files via the torrent network). This taxes the hell out of my windows machines and they are accordingly slow. I'm guessing then the MBP would be better for me over MB and MBA? Also useability is really big for me..I'm splitting hairs right now typing on the CR 48 because every 30 seconds my finger will inavertantly hit the touchpad and my cursor will cause me to type random in random places which is REALLY annoying for typing up lab reports and the like. I understand I could stick with Win7 but the reason I'm strongly considering the switch is because of design. I'm mildly offended that none of the PC vendors (HP, Dell, Lenovo, etc) couldn't get the idea of simple design beauty down the way Apple has. MPH says 'use me'..my Asus netbook and IBM thinkpad on the other hand look like a POS. Last thing for me is a SSD. I'm 100% sold on the SSD drive after experiencing it on the CR-48, I LOVE the speed. And I have a 500gb external. Cost is an issue for me in that I'm trying to reduce it as much as possible. The version I have configured now with education discount is the entry level one but with a 128 gb SSD comes out to $1324. Do you all think this is good and if so when is the best time to get it. I want to maximize the amount of stuff I can get so if I could get the educational discount + the free ipod or ipad that would be great. Would also appreciate any reccs on cases although I'm sure there are some guides on this... Sorry I know this post was a lot!
