I'm gonna agree with Dempsey 100%, right before I tell you why I disagree.
Those little Baofengs are absolutely no match for a proper mobile radio in the mobile radio's element, and for what 99% of guys on this board are going to use their ham for, the mobile is 100% the way to go. HOWEVER - those little Baofengs can leave your rig if you want to (or have to) strike out on foot and keep a radio with - most mobiles can't do that. Those little Baofengs can be loaned to a non-ham friend in case of emergency (or even just to listen in to the chatter on a group run). They can listen in on the FRS and GMRS frequencies that those little blister pack radios use (they can transmit on them too, tho that's not legal). And they're so cheap they're practically disposable.
Notwithstanding everything that Dempsey has said about a little HT paling in comparison to a proper mobile setup, and everything he's said about Japanese radios being generally better than the Chinese, I still don't think there's any reason not to get a little Baofeng UV5R or BF-F8. It will never be a decent substitute for a good 50w unit with a real antenna and you should be looking at spending $200-$300 at least on a good mobile unit. But get a little Baofeng anyway to screw around with while you're shopping for a real radio, and then once you've got a real radio toss the Baofeng in the glovebox or a backpack and have a spare/loaner.
