Also consider what type of contractual commitment you're willing to sign. Dish and Directv lock you in for two years, and Dish has a lot of programming disputes where channels might go off the air temporarily or permanently. Oftentimes, cable is contract free and you can "walk away" basically at any time, though I hear some cable promotions from some companies are starting to require contracts, so you might want to look into whether you can get any good price promotions contract free in your area.
In your shoes, I'd probably drop FIOS and switch to contract-less cable offering for your current apartment. Then, if you want a dish, get it at your new place. The main reason for doing cable now and Dish later? There is often a moving fee for the second setup at the new place. If you wait to get it until after the move, you may get free installation (Though an important caveat here is that Dish runs a credit check on you and makes some people pay for install- cost me $99 despite their advertising and they didn't give me HD equipment, and, yeah, I'm still a little bitter), and there is no possibility of a moving fee.
Another factor to consider: Where are you getting your Internet? The Dish/Direct bundles are usually with DSL- which is relatively slow even at it's best, and can be really difficult to deal with if the telephone wiring infrastructure in your area has gone to hell (Which is beginning to happen more and more as people switch to using cell phones as their only phones and the telephone companies don't put the money into keeping phone lines in as good of repair as they used to, or at least that's what it seems like).
Right now I have Dish for TV and the local cable company for Internet. That works out because I have a great promotional rate for the Internet. Once that rate expires, I will get hit with a non-bundling fee, and because there is no FIOS in my area and the phone lines weren't even good for voice calls when I had a landline, I may wind up switching my television to cable in part to get a bundling promo. I do think there is one Internet package that doesn't have a "no-TV" fee, but it's a little slower than standard and costs a little more, so I'm not sure whether it's worth it (Might be worth trying for a while to find out).
I guess my post is kind of sounding pro-cable, but that's not necessarily the vibe I'm trying to send. I've had issues with cable too. Comcast didn't carry the alternate games of a local regional sports network in my area, even though they do to the east, west, and south of me (Not kidding). Then Comcast added it for a season. Then Comcast took it away the next season. And no one I talked to even seemed to know what I was talking about when I called to complain. And when I cancelled my TV and Internet with them and went back to get Internet 6-7 months later because the wireless broadband card thing I had from another company was horrific, they claimed my address didn't exist (Even though I had service with them at this same address 6-7 months prior) and I went through hell trying to get Internet back up (Only a slight exaggeration- a zilllion phone calls, two or three office visits, two or three visits to my apartment, a missed installation appointment, a letter to the consumerist, a bunch of e-mails, more phone calls, and finally an appointment I only agreed to because they sweetened the pot and made the deal impossible to pass up- otherwise I would have told them to forget it after going through all that).
One thing I'll say about Dish positively is that- despite their contracts, their discrimination against people with low credit, their implying your first year rate is locked in when it's not, and their frequent programming disputes that lose you channels you need- they are actually fairly easy to deal with. When I called to install, they had people out here within a couple days. Service calls, the same. I can switch programming packages right on the Internet. That is one area that they are way better than cable in.
