Hi guys, I am a windows administrator and I have been thinking about buying MacBook Air 2013 13" since July 2013. Unfortunately, I am not 100% sure. Let me describe what I need to run on it: 1) Crucial: "microsoft" VPN, Cisco and Fortigace VPN clients, microsoft VPN, SSH client, FTP client 2) Not crucial, but necessary: watching movies, listening to music, python scripting, c++ programming My Mac will not be added to the MS domain, it will serve just like a client for VPN and RDP connections. I would like to ask you to answer my questions below. 1) Is the MacBook Air 2013 13" overheating? 2) Do you have experience with connecting to the Microsoft VPN, with using CISCO and Fortigate VPN clients? Should I beware of something? 3) What about Microsoft RDP client? Have you experienced any issue with it while working on a remote MS server/workstation? 4) And now one of the most controversial topics. Would you recommend me an antivirus or not? Alternatively just a firewall and which one? 5) I cannot decide which configuration to choose: 13" Air i5 1,3GHz, 8GB ram, 128GB SSD, EN system 13" Air i7 1,7GHz, 8GB ram, 128GB SSD, EN system What do you think? Unfortunately, I have not got a friend or a relative who can help me answer my questions. We all are running MS Windows. Thank you for all your anwers.
