Here are 5 predictions for Apple hardware and devices that could be released this year at various Apple events. I'm leaving out any thoughts about an Apple TV, partly because my guess is that it still might not come this year.
1. iPhone 5
Apple releases iPhone 5 in July with 4.6 inch screen and all new 1280 x 720 resolution display with new aspect ratio and curved glass. If they keep the same aspect ratio as the iPhone 4, the resolution would be something like 1200 x 800. Either resolution would have 300+ ppi display, which is similar to the iPhone 4. Previous iPhone apps would work at their original resolution covering only 3.5 inches of the screen and all new apps for iOS 6 would fill the screen. 4.0 inch display for the iPhone with the same 960 x 640 resolution is my second, more realistic guess, and much more likely.
2. iPod Touch 5G
iPod Touch released in September with same sized screen as iPhone 5 and a 3-5 megapixel camera. Possibly renamed to simply iPod. Likely won't happen but could finally get GPS and 3G version with some kind of data plan or new type of 3G plan that pleases carriers enough to make some money off iPod users while encouraging most people to still get an iPhone because of LTE or better and more powerful cell plan features.
3. iWatch 1G
iWatch 1G is released in September with iPod Nano OS and possibly a curved glass screen. It will have Bluetooth 4.0 which allows it to work with iPhone and other iOS or Mac devices in interesting ways and will focus on some built in fitness features. I've thought for years that Apple would get into the watch business and this could be the year. Good chance it may not happen until 2013 though and the Nano stays around for another year or two.
4. New iMac
The new iMac is introduced in the summer with Mountain Lion OS X and a new slimmer design similar to the Apple Thunderbolt Display. Ivy Bridge and maybe even 8 GB RAM standard. Possibly also bumped to 23.5 and 30 inch displays. Comes with no optical drive or hard drive, or even an option to install an internal hard drive. 128 GB or even just 64 GB SSD standard, especially if Apple also markets a new external drive peripheral or Time Capsule for always on networked media libraries. New Bluetooth 4.0 peripherals including keyboard with even slimmer profile, new Magic Mouse, and Magic Trackpad. Possibly a keyboard with integrated Magic Trackpad that will also work well as a single peripheral to have on your lap when using AirPlay Mirroring from a Mac to an Apple TV 2.
5. New Time Capsule
Though I don't think this one will happen, I wish Apple at some point would release a new external drive peripheral or new version of Time Capsule used for always on, Internet connected, networked storage. It would be a person's or household's own file storage and media library that could be connected to from their Wifi network or over the Internet from any Apple devices. If everyone had their own personal storage device that was always on at their home and Internet connected then they would only need 64 or 128 GB flash storage in all of their devices and would not need to pay for higher storage capacities on services like Dropbox, Skydrive, Google Drive, iCloud, and iTunes Match. Because of the money they can make and the investment in iCloud and iTunes Match they likely won't do this, so this is more my own vision of the way I wish things would go. But Apple could change the game if instead they switched course from everyone else and instead offered hardware for a person to host their own simple always on file library and server at their home instead of relying on pay cloud storage services like Dropbox and iCloud.
What I'll Buy
I'd probably buy an iWatch if it was made and sold for $199 or less as it would be pretty cool, though I might wait for version 2 like I did with both the iPod Touch and iPad. I also have an iPad 2 and the new Apple TV, so Apple is obviously reeling me in to buy their stuff like they are much of the population. But really what I'm excited for and really ready to buy is a new iPod Touch if it comes out this year with an all new design. I still have a 2G iPod Touch, which is the only iPod I've ever bought and of course it runs too slow and is getting old. Mobile computers dating back to the early Palm Pilots are really what has always fascinated me. Even with how common they've become as they've evolved into subsidized smartphones it is still fascinating to me to have a powerful computer in your pocket and hand, and it always will be. Before my iPod Touch I had a simple Palm Z22 that I liked just as much or more than my iPod Touch.
There is an outside chance I might spend the extra money and finally make the switch to Mac OS X from Windows 7 with the new iMac this year. I've wanted a completely silent desktop computer since only about 1992 and have been disappointed that computers have been so loud and hot in the last 20 years, and that it has taken so long for quiet and cool computers to be common. Though I know they are already very quiet, the new iMac or Mac Mini could finally offer a really silent desktop at a reasonable price if they are sold with an SSD as standard at their current price and with Ivy Bridge bringing some more improvements in thermal efficiency. That, along with so many other well known reasons that have made Macs a much better option in the last 5 years, I might finally be pursuaded to make the Switch and get my first Mac. But maybe I'll just stick with Windows 7 for a couple years until about 2014 when some new version of Mac OS or Windows 9 are running on 64 bit ARM processors, don't even need any fans, and 256 GB SSD drives are in cheap machines. But I just don't know if I can stand my current Windows machine sounding like a jet engine is on all the time under my desk now that I'm used to completely silent iPods, iPads, and Apple TVs.
