Hi, Any advice? A long term MBA user since 2010. I've had four models. Currently have the 2013 base 13-inch. Wondering which would be faster most hassle free for everyday use: chrome multiple tabs, Zotero, Word, Nisus, plus some reasonable heavy graphical 300 page PDFs. I usually have all of the above open plus iMessage, Mail, Calendar, and the odd FT call. This is entirely subjective, but as software demands increase, the Airs seem to be getting slower and less 'instant' for multi-tasking, despite CPU improvements. The choice is: MBA - 13-inch - i7 - 8GB - 128 GB (I don't use much storage not bothering with photos or films) MBP - 13-inch - i5 - 8GB - 128 GB SSD (bto) Just want a system which is nippy and reliable. Portability and battery life is not a concern. The MBP screen resolution seems better for anyone with eyes over 40 years old.
