I was a huge skeptic of the iPad when it was launched. But now I'm glad I bought one.
Increasingly, I've been involved in a few management projects in my hospital & I wanted something small & portable to write reports and make presentations. As there was no other decent tablet on the horizon (there was a long waiting list for Asus Eee Pad Transformer), & the fact there were already 70000 apps exclusive for iPad, I decided to buy one (32GB wifi only model - mobile tethering with my HTC Sensation works seamlessly). Being the most successful platform, I knew that there won't be an app maker not targeting iPad.
There are a few medical softwares which are brilliant. The biggest eye opener for me is iWork, especially Keynote (like powerpoint). I'm still getting to grips with numbers (like excel) but some of the features are way superior to MS Excel (although I don't think they're as elaborate as Excel; I may be wrong here). They're brilliant, & so easy to use! I'm yet to convert them to Microsoft compatible files, so cannot comment on how good they'll look on MS PowerPoint presentation or MS Excel. But converting excel files to numbers to edit is not the best.
Most importantly, both me & my wife have almost completely stopped using our laptops (mine is a Windows 7 & hers is a macbook). The user interface is superb. With upcoming iCloud, you can store all your photos in the cloud, freeing up hardware space.
There are situations where iPad is lacking, most of which will be resolved after the iOS 5 update (as I'm used to Android).
There's no denying that Apple makes some of the best hardware & software today, but I don't agree with their restrictive policies & such tight control.
I wanted a tablet this year, & iPad is still the best. I'm almost certain I'll buy an Android tablet in a couple of years' time (by which time there will be enough Android tablet specific apps & being an open platform will offer me more flexibility).
Now only if Microsoft decides to release MS Office suite in iOS......it will certainly make a killing!! iOS & Android are huge untapped goldmines for Microsoft.
