As with Cotton, I haven't experienced most of the issues you have had. I do have an alignment issue with the right side b-pillar hook that I've been meaning to get addressed at the dealer, that will come up when the oil change is due. If you think the top operation is a not-funny joke, you must have been very spoiled in the past. I've had other cars with worse tops. Some of your "bad" issues are really finicky things...you won't find a convertible on the market in the same price and performance range without little things like that.
The engine sounds you don't like are likely a function of the direct injection system, which is the only unusual sound mine makes...unusual because I've never had anything with direct injection before. Comparing to an S2000 engine is a bit silly, that engine has less power (which you have to rev the hell out of to get because it has half the torque), and gets worse fuel economy. If you want to reduce the sound (not eliminate it, but reduce it) you can get one of these for a few bucks, I plan to do it myself:

In regards to the tires squeeling...well, duh, you've got double the torque that most of the competitive cars have...tires will squeel. Get stickier tires if it really bothers you, personally I'll wear these ones out (shouldn't take long!) before I get stickier tires. You also grip about the traction control killing power...well, these go hand in hand. You don't want the tires to squeel on launch, yet you do want them to chirp/slip during shifts? That's what the traction control button is for...if you want max power, hit the button twice to go into competitive mode...I agree, for more skilled drivers this is a heck of a lot more fun. However, I like that if a friend wants to take it for a test drive or I'm driving around in the rain, the regular traction/stability control mode is conservative.
Complaints of window switches, cup holders, wiper controls, etc. are really finicky IMO. Would I do it different if I was in the design team? Sure. Is it worth complaining about? Definitely not. Here's where somebody who purchased the car would be more satisfied than someone who got the car for free. I compared the Sky to the competition. Other cars had nicer trim and ergonomics, but compromised performance and had bland looks, which is fine for somebody purchasing an MX-2000. I wanted a sexy roadster with some balls, so I bought the Sky. Want a car with great ergonomics and great power? Get out another check book.
When everything is adjusted properly for me (6' - 180 lbs) I can see/fit fine, although my head will definitely rub the top with a helmet on, same as on all my other small cars. Taking friends for a ride should occur with the top down. What fun is a roadster with the top up??? I'm really confused how the steering wheel blocks the traction control button. It's next to the shifter. How close is your face to the steering wheel?
No lift shift is a feature of the turbo tune available from GM Performance Parts. 30 hp, 65 ft lbs, no lift shifting, factory warranty maintained for about $700. It's amazing how quickly you can get over the shortcomings of the Sky/Solstice when you have double the torque and a whole bunch more power than a Meotter and S2000. I also love the way it looks. That's why I paid money for it, and why I appreciate it as an awesome alternative to the competition.
