I've got one. 9343 model. It's amazing. I run linux on mine, so the battery life isnt quite as good, but I get a good 7-9 hours of light use from it. (word, blackboard, etc...)
My model came with the following:
- I5-5200u (2.2GHz -> 2.7GHz)
- 8GB ram (soldered onto motherboard, so there's no upgrading this)
- 1080p display
- 128GB m.2 SSD (upgraded this to a 500GB samsung SSD)
- broadcom wireless (upgraded to the intel one, because linux support is better, nothing wrong with broadcom on windows)
The trackpad and keyboard are, in my opinion, very nice to use. Your finger doesn't stick to the trackpad like on some models, but still provides a bit of resistance. The keyboard has a nice feel to the keys, with a low activation force. The screen is quite something too. I just can't put into words how nice it is to have such a space-efficient screen. That was one of the determining factors for me when I purchased it.
The laptop is pretty powerful as well, you may not notice the power as much if you're running windows, but who knows what will happen in two years. I'm able to do pretty much anything I want short of running intensive games on it.
The laptop itself feels very solid, taking both size and weight into consideration. Obviously, it won't stop a bullet, but if you drop it off the table, it should be fine because there are no spinning parts aside from the fan.
The only downside I see is the cooling. Dell has done a decent job with it, but it still gets up into the 65C range before the fan really kicks on. Maybe I just prefer lower temps, but that's just me. That said, when I'm compiling something, it won't pass 85C and as far as I can tell (haven't bothered to benchmark it) it doesn't thermal throttle.
All in all, it's a solid laptop and I'd say it's probably one of the best options out there if you have the cash for it.
If you've got any questions about the laptop, let me know.
That said, I'm sure they'll have made some changes by the time you're ready to purchase.
