I like Nintendo. I have a long history with them. I grew up with the original NES and SNES systems and did buy the original Wii near launch. At the time it was a good value: half the price of existing systems, innovative waggle/wiimote interface (which my family still enjoys to this day) and good-enough (at the time) SD graphics.
However, a few years in, when the PS3 price dropped to about $250 I ended up buying one. Why? HD and Internet gaming. The Wii's graphics where no longer consider worthy of my new HD TV and its tiny flash drive and poor online interface were a joke compared to the PS3. In all the years I've had the Wii, Nintendo barely updated the software and never really added any new, interesting online functionality.
Now, with the next console generation soon to be upon us, Nintendo has released their next console, the Wii U.
Nintendo has seemed to not have learned any of the current generation lessons. The Wii U has, in my opinion, some major drawbacks:
With all these drawbacks I'm finding it hard to to see how a Wii U is better than the current PS3, never mind the future PS4. The PS3 has comparable graphics, more storage, a larger game library and to top it off, plays Blu-Rays!
I'm not claiming to say this will be Nintendo's last generation of consoles - they've survived worse. But I do think they've screwed up with the Wii U and will pay for it in the upcoming console generation.
