WiFi... One feature of the phone. Useful in some situations, not in others. Remember: The stock settings on the phone leave it crawling and hobbled. Limited program memory because of too large a page pool. Extra junk loaded that most people don't use. Can't even watch the movies that it itself makes.
It's a "Good" phone the way it comes. Cook up a proper ROM and suddenly you can have a GREAT phone. Microplan + Unlimited Data Plan + Skype (With proper tweaking) can be Very Fun.
