Here's the situation.
I have a good ASUS laptop, i7, 8GB, 15.6 inch screen, works fine. It runs Lightroom and is slow, but manageable if I don't have to do too many pics. This laptop is 4 years old. The problem with it is that it is bulky and heavy, and has a bulky and heavy AC adapter. It is a pain to take on a trip.
So I have been looking at maybe replacing it with an Ultrabook. These are much smaller and lighter and very neat looking, but very expensive. One of these would be much easier to take along on trips, and also much better for use while on the plane.
But these expensive Ultrabooks seem to use i5 chips. So my question is whether they would end up being even slower than my existing bulky Asus.
