It's 2009 and my Asus Laptop has just crashed due to an update from the manufacturer causing the device to brick. While my journey to iOS 5 and OS X Lion hasn't been so dramatic, I'm certainly getting flashbacks of that fateful day I knew the laptop I had chosen couldn't function as a reliable consumer device, let alone a work machine.
In the last few days since I've made the switch to OS X Lion, I haven't encountered as many problems as I did when it was first released. Not being able to retrieve my email from my @me.com addy is maddening to say the least. Migrating from MobileMe was painful, like bidding a trusted friend farewell.
iCloud (MobileMe's successor) is buggy, prone to gaps in service, or it just doesn't work. I've spent some time exploring it's functionality and only the Calendar and Contacts syncing services seem reliable. Everything else either fails, works half the time, or not as intended. My iOS devices seem to be weathering the transition better than my Macs, which at least gives me an option.
Bottom line, I'll be seeking out replacements for the services iCloud provides and using my Lenovo Thinkpad to generate the more important text for my work. At the core of the issue is OS X Lion struggling to interface with and manage the cloud services Apple provides. I'm thinking they'll be fixing those things pretty quickly, but I've been wrong before.
If you haven't yet migrated your MobileMe account, upgraded to iOS, or made the switch to OS X Lion, I'd go ahead and wait a while longer.
