Any of you N900 users, or anyone who used to use the N900... have you found a tablet that you feel compliments the functionality of the N900?

My N900 is about to go in for warranty work and I have a feeling it will just get replaced with the N8 or E7, I doubt I will keep either and will just go out and locate a very basic dumbphone with a strong antenna. I have gotten damn near addicted to being able to do server administration on both Windows (RDP) and *nix boxes (both redhat and solaris via SSH) while on my N900 at work, so I am hoping to be able to replace the N900 and not have to lug around my work laptop. I work in a large data center and clock in about 4mi a day on the pedometer widget, so carrying around a laptop has just not worked.

I'm shopping for a possible tablet option, but I wanted to see if anyone has used a tablet that they would endorse, or if they disliked a tablet, why?
