I was always a big fan of Dell Laptops and accordingly bought Inspiron 7373 2-in-1 laptop. This was my biggest mistake. Some of the clear disadvantages include:
Very less battery life. On full working mode it doesnt even last an hour
Doesnt wake from hibernate or sleep mode. Every time needs to be restarted with power off button which is a big pain. Dell has no solution to this and are not even bothered to release any patch for this. It seems its more of the hardware issue rather than the operating system.
Extremely noisy fan. Cant work in peace and it gets heated very fast.
All in all dont waste your money on this laptop
