If you loved the 2XL, you will LOVE the 4XL. I didn't at the very beginning of owning my 4XL but that's because I chose to get the 3XL first, then two years later the 4XL. I didn't like it at first because I was expecting similar hardware like the fingerprint scanner and didn't do my research first, same with things like the 3XL has, but the 4XL retired. My point is this, as long as you're aware of the changes between 2XL and 4XL hardwar-wise, then you'll absolutely LOVE the 4XL!! I made the mistake of getting the 3XL before my 4XL but I should've just kept my 2XL until the 4XL. The 4XL is flippin amazing and it's used 75% of the day for work (I do everything that doesn't require me to access the cloud) through my phone, the cloud work through my PC so I use my phone and rely on and need my phone, very much.
It's my daily driver and I plan to keep it and use it until the hardware blows up. I still get TWO days idle battery with plenty to kill so it lasts forever.
