At levels that low, I have to concur that Warlocks are boring, though the UMD does mean that if they have access to markets where wands or scrolls can be bought they're good emergency-backup casters. My 5th-level Warlock was never without a wand or two of Cure Light Wounds, which with his maxed-out UMD and decent CHA score he could always use at will (taking advantage of the ability to take 10 on the check under any circumstance).
Once the Warlock starts getting access to his Lesser Invocations, though, things can become a bit more interesting. Personally, I've never understood how people seem to constantly harp on Fell Flight as the best one to take at 6th; for me it's all about Flee the Scene- I mean really, Dimension Door (admittedly, short-range) at will, and you can even take other people with you? Explain to me how this does not help the party! And then allow me to prove you wrong by pointing you to the Story Hour forum to hunt up JollyDoc's Age of Worms, which features a Warlock PC played from about 8th level all the way to the end.
For me, Warlocks really start coming into their own at that level- sure, they have few tricks, but if you pick the right tricks they're a serious force to be reckoned with- and a real "blast" to play (pardon the pun).
