Holy shit Dave this is worse than buying a car. I just need the equivalent basic transportation, no gaming here. Don't care about sceeen size or memory, everything she going on outboard drives. Might just go with first choice if it lasts five years I'll be happy. I do everything except music processing on iPad.
Marc, in my humble opinion and for your stated basic audio processing needs, the machine(s) you've picked out should be just fine. The only thing I would change on either of your choices is that I would up the RAM to 16gb.
I tend to agree. If it were my choice out of these two: I'd go with the Win10 machine but make it 16GB RAM as billydee suggests. For that price, if it lasts 3-5 years you will have gotten your money's worth.
I HAVE used Lenovo, and purchased them for clients; no build complaints aside from that odd track eraser thingy; HOWEVER warranty work is 100% mail-in which I and my clients find not optimal. Mine is a work situation, so you would probably be fine, just no computer for the 5-10 business days it takes to process.
One aside; for any laptop, buy the longest, best warranty you can afford. (i.e. I ALWAYS get Apple Care on a iPad, but rarely get accidental coverage on Dell towers. [same type of warranty/different names])
