but my friend's iPhones are blocked from getting new features like Siri even though the hardware is perfectly capable.
Siri is still Beta. Unlike Google, Apple restricts access to Beta software. They may open Siri up to earlier devices like the iPhone 4 and iPad 2 once it is out of beta, if the experience is acceptable.
2) The apps are lacking on Android
There is a real lack of apps for iOS because so much is blocked from the App Store. Casual developers and open source projects won't pay the high fees and it also means apps tend to more more expensive and there are fewer free ones.
The quality of the Apps in the iOS App Store is much higher than in Android. I wouldn't call $1000 for a Mac Mini and $100 for a Developer Account to be particularly high fees.
Free Apps in the Android Store are supported by advertising. I think paying $0.99 to not be bombarded with Ads or have your usage data sold to the Highest bidder *and* the lowest bidder (and everyone in-between) is a fair price.
3) Hardware software compatibility.
The dock connector really sucks. What is wrong with USB? I have to carry a special charging/sync cable, and I have to use the shitty iTunes software just to copy some files off the damn thing.
The dock connector was a great replacement for FireWire of the earlier iPods. FireWire could only carry Data and 12V Power. The Dock Connector could also carry 5V Power and analog audio. It was upgraded to also carry analog video. It was upgraded to also carry Digital Audio, then Digital Video, but they had to strip out 12V power. I don't think we'll see Thunderbolt iPads soon.
Yeah, iTunes for Windows is pretty crappy, even though it still the most popular music playing Program on any platform. It's quite embarrassing. The only thing more embarrassing would be Zune, HTC Sync or to not have any Syncing Software at all. Windows Phone 7 Connector for Mac is not too bad though...
I've also had more luck buying Dock-connector USB cables than micro-USB cables anyway. I needed one for my AppleTV the other day and tried three different electronic shops before I found one. I should have just bought one of those $40 Android Phones instead, thrown it away and kept the cable.
4) The hardware is sub-standard by most, not all vendors in comparison to Apple.
I'd say it's much better generally, at least on comparably priced devices.
Unfortunately for Android, those comparably priced devices are few and far between. Most Android devices on the market are cheap, nasty devices being sold at inflated prices. Same reason why Windows has such a bad reputation.
Now, a few points of my own:
5) No user changeable battery. I push my phone quite hard and although battery life is better than what my friend's iPhone seems to get eventually that battery will wear out, and I want to be able to change it.
Apple have a repair policy for the battery. You will still be able to get a replacement battery for an iPhone in two years time when the battery finally does degrade to the point of being unusable from any of the Hundreds of Apple Stores around the world, or from any of the Millions of iPhone repair booths dotted throughout Shopping Centres and Malls around the world. If you need to power up on the go, Morphie Juicepacks and cheaper knock-off Dock-connector battery packs are sold at most Corner Shops.
You may have some difficulty finding the exact battery for a 2-year-old Obscure Android Phone.
6) No SD card, and I need iTunes just to access the damn thing. The amount Apple charges for an extra 16GB is outrageous, more than I can get a 64GB SD card for.
Are you able to put Apps or other Protected content on SD Card in Android yet, or are you still restricted to Internal Memory? Legitimate Question.
7) No USB host support, I can plug any random USB gamepad into the Transformer and it just works.
iPad Camera Connection Kit allows you to connect Keyboards and USB Sticks with DCIM data. Why are you connecting a Gamepad to a Touch-Screen Device? Legitimate Question. I've never tried it with an iPad because I've never felt the need.
8) Lack of multitasking. I often want to copy/paste from the browser to Colornote or an email but on iOS you have to close each app before going to the other one. There are no background apps either, for instance I use a GPS logger while I am taking photos on my DSLR so I can geotag them later and it does it quietly while I can look at maps etc. without closing it.
Which version of iOS are you using? User-side Multitasking has been available since iOS 4. Legitimate Background Apps are forced to behave nicely. There is a plethora of Background GPS Loggers in the App Store, all with the disclaimer "Continued use of GPS running the the background can dramatically decrease battery life". No wonder you need to replace the battery on your Android Phone if you are using it as a GPS Logger.
9) Poor screen. The iPad 2 screen is only 1024x768, too small for web browsing IMHO. I upgraded my old Thinkpad laptop because the screen was only 1024 pixels wide and would never want to go back to anything under 1280 now. My 12.5" Let's Note is 1400 pixels which seems to be about the right DPI.
I prefer browsing in 768x1024 on my iPad. I can instantly zoom in on most websites. The handful of sites that are crippled on iPad generally aren't worth visiting anyway.
10) Expensive accessories and peripherals. Apple charges silly money and seem to be keeping official 3rd party prices high too. You can get knock-off stuff but it tends to be crap, where as on Android I can use generic but good quality peripherals costing 1/10th as much as the iPad ones.
Yeah, I agree that Dock-compatible devices are more expensive than their generic counterparts, but most high-end product is more expensive than generic counterparts. The iPhone's and iPad do work with most USB-host music players I've experienced, even the cheap, nasty ones. I haven't seen a car stereo with a USB Socket that doesn't integrate flawlessly with the iPhone or iPad, or any iPod since the FireWire-only 2nd Generation iPod.
11) Page display in the browser. Android has reformatted pages since day one to make them readable on a phone screen, but iOS doesn't seem to do it. OK, not strictly tablet related.
See #9 above. Maybe your holding it wrong
Can't wait for the new Transformer.
I can wait for the iPad 3. My trusty 1st Gen iPad is still performing admirably.
