Meh, the basic system isn't so bad. If you want to download games, you'll need a hard drive with either system, so losing a few GB internal memory really isn't such a big deal. If you prefer retail over digital then the lacking hard drive won't be a detriment for now anyway.
The real question is whether or not you want to drop $200 on a console with so few games worth playing at this point. There will be good software - both the usual Nintendo first-party exclusives and some third-party games ports. But right now Wii U is looking pretty barren, so people would have to be buying with an eye to the future. (That said, the Xenoblade sequel is almost justification enough in my mind... and off-TV play would be invaluable in this household where I rarely get to use the living room TV between my kids and wife taking their turns.)
For what it's worth, reports are that Walmart will be blowing out their Wii U Basic stock for $200 next week also. I'm not sold yet - but will think it over. Does Wii U upscale Wii games by any chance?
