My MPB 17 (Week 23) Review

I'm a long-time powerbook user, and just upgraded from a 15" AlBook (first generation) to a 17" MacBookPro. Here is a brief list of the good, bad and ugly. I'd consider myself a power user (programmer & database development, lots of VirtualPC / Parallels use) so my perspective may not be that of the average user.

The MacBook:
17" with 120gig drive, one gig of RAM, matte display.
I upgraded to 2 gigs of RAM with a generic RAM stick from a local vendor.

The Good
• Delivery / Shipping -- was quoted 10 days from order to arrival, the MBP actually arrived within 48 hours. It made it from Shanghai to my doorstep in under 23 hours! Perhaps FedEx should get credit for this. However, my coworker's order did not fare so well (see below).

• Noise -- this is one of the quietest laptops I've owned or used (over a dozen in my life). Several friends (all who can hear the "Mosquito" sound that's been on the net lately) could not hear any high frequency noise. If you max out both processors, there is a very slight fan noise. Hard drive is whisper quiet. There is a very slight "morse code" sound from the CPU, but it's only audible if you put your ear to the macbook, and it is much, much quieter than the similar sound that my G4 AlBook has.

• Screen -- big & bright. In terms of brightness & saturation, it makes my apple 20" Apple LCD display look a little washed out. Previously, I would have called the 20" display "the best I'd seen". The viewing angle is, of course, better on the 20".

• Build quality -- the case is good, screen closes evenly, lid is even (but see below)

• Speed -- it's fast. Way fast.

The Bad

• Heat -- using CoreDuoTemp, I'm seeing temps of about 60C to 65C when idle, which seems high to me. However, if I max out both processors, the temp won't go above 85C, and I can hear the fans turn on. The bottom of the case gets blazing hot, noticeably hotter than my 15" AlBook (which I thought was hot). All in all, I can live with this -- in practice it means no using on lap while wearing shorts.

• Migration Assistant -- after transferring over 60 gigs of data, I had some problems:
1. My spotlight index was fubard. Searches in Mail would only find about a dozen mail messages for a certain keyword (where I know there are 1000s of matches).
2. Static IP address problems -- I had a couple of static IP address network configs which did not seem to work right after transfer. I re-built these from scratch which seemed to fix the problem.

• Delivery / Shipping -- a coworker ordered a CTO macbook at the same time, and his has now been in FedEx's system for 3 days, and mysteriously was routed to Indiana from Anchorage (for delivery to Southern California). Mine came directly from Anchorage to SoCal.

The Ugly
• Screen Hinge -- if I tilt the macbook towards me, at around 45 degree tilt the screen will start to close. If I'm not paying attention, and tilt it further, it slams shut with some speed. This makes it unusable when lying down in bed or on the couch. Reading these forums, it looks like this may or may not be a design or build flaw. I may call apple to get their perspective on a fix.

• Screen bezel is sharp -- yesterday, the screen slammed shut on me and actually cut my thumb! The inner lip of the aluminum bezel is very very sharp. On my 15" AlBook, it's not quite as sharp, and the screen stays open so it's not an issue. I'm not the litigious type, lucky for Apple.

• Freezes & Kernel Panic -- I've had two freezes and one kernel panic in 48 hours. All three incidents happened within 5 minutes of waking from sleep, and two of the incidents happened when using a non-Apple wireless network (an old netgear box). One happened before I added the 2nd RAM stick. I've turned off hibernate, turned off IPV6, and things seem a little better now.

Summary
If I can't solve the kernel panics & freezes, the machine will be unusable. I'm hoping that these are software bugs that can be fixed by 10.4.7. I'm not sure if I can live with the loose screen hinge. Otherwise, the machine is quite good. I'll report back in a week or so with more thoughts...

Update: after writing my first post, I had another kernel panic, while using Airport.

Since then, I've rebooted, turned off Airport and plugged into a wired ethernet network. I've been running Parallels, surfing the net, streaming iTunes music, reindexing Spotlight and re-building large mailboxes in Mail. After several hours I'm panic-free. I've also run extensive RAM tests that came back clean.

Based on these symptoms (which other folks seem to share), I'm suspecting these kernel panics are due to some sort of Airport driver bug.

FYI, here are a couple of panic logs from /Library/Logs/panic.log

Here are some more thoughts after 3 more days of use of my Week 23 MBP 17".

Whine
Ugh. After 3 days of use, the processor whine has gotten MUCH louder. I'm talking about the sizzling morse-code like shh-shhhhhhht-shh-st-st-shht noise, which is only present when plugged into power, when the CPU is idle. I can now hear the noise in a quiet room from about 3 feet away, and it's making my left ear hurt. I'm not exaggerating when I say that it feels a little like the newer high RPM drills that dentists use -- it sets up a similar reverberation in my jawbone. Yuck. This is simply not tolerable. How could this have slipped through Apple's quality control?

Note: I just downloaded and launched QuietMBP http://www.red-sweater.com/blog/downloads/QuietMBP.zip and it removes the noise completely. I notice no significant CPU usage. Since I only have the noise when plugged into power, this may be a reasonable solution.

Screen
The 17" screen is very bright and has good saturation. However, I'm finding the viewing angle is somewhat restricted (as compared to my previous 15" AlBook). For example, trying to use the MBP in bed, I find that it takes a lot of fiddling to get the angle just right. Since the hinges are loose, this is hard to do, as the screen keeps slipping to a new angle.

I don't use my 'book in bed too often, but if I did, I might think this was a deal-breaker of a problem. Right now, I'm willing to live with it.

Performance / Heat
Wow -- I played the free demo of WingNuts for about an hour. Graphics performance is beautiful. The bottom of the case got quite hot, but was tolerable. This was with the MBP on battery power alone. Playing a 3D game while plugged in may be too hot for comfort.

Freeze / Kernel Panic
After several kernel panics, I decided to switch to ethernet and stop using airport. I've been KP free for 3 days now. This strongly suggests the KPs are due to Airport. I can live without Airport for a while, but obviously that's not an acceptable solution for long-term. I still may call apple and try to get it declared DOA and return it, or I may wait a bit longer and see if it's a driver bug that is fixed in 10.4.7?

Stay tuned...
Our 2nd MPB17 just arrived by FedEx this morning (after 6 days in the FedEx system...grr...). After we open & configure the new one, I'll report back on any significant differences between the two.
