I own a HP Pavilion DM4 3013CL laptop with an Intel Core i5 processor and 8 GB of Ram. I recently purchased an Acer Switch 12 SW5-271, a 2-in-1, 12-inch laptop / tablet, with an Intel Core M and 4 GB of Ram.
For me, the biggest difference is the Acer Switch 12 stays cool and does not burn my lap.
|Processor||Speed||Laptop Heat||Fan||Battery Life|
|i5||No obvious difference||Gets hot after an hour of use||Yes. Loud.||2 to 3 hours.|
|M||No obvious difference||Stays Cool||No.||4 to 5 hours.|
