Kim, I am also REALLY HOPING for a laptop with normal keyboards we used to have on old Dells with Ins/Home/PageUp/Del/End/PgDn block. All these new combos of putting these buttons who knows where or merging them with other buttons via FN keys are driving me nuts. They are completely useless for development work with a normal IDE which often needs combos like Ctrl+Arrow or Ctrl+Home or Ctrl+Shift+PageDown. That specifically on M3800 and the likes (i.e. Lenovo Yoga) would need freaking 4 keys together.
I also really really want to see a laptop with IPS 1920x1200 panel as 1080 is not enough for me.
From the perspective of such keyboard, I was holding on to E6410/E6510's for a while, but then made an upgrade to E6530 which allows 16Gb RAM easily. What I also did was replaced LCD with a Full HD IPS panel. There's no direct match that would fit right in, however, E6530 lid has enough space to put newer IPS panels like LP156WF4(SL)(B2) after removing a few things like indicator lights and some plastic pieces. Overall, besides the sucky keyboard that E6530 has, that IPS replacement was really worth it.
I also tried E7440 which comes with a Full HD IPS screen already, but it seemed at 14", letters were a bit too small for me. Another problem is that the IPS version is touch-screen and is glossy, while I really need Matte panel.
