Someone mentioned it earlier. The iWork suite is very, very good in my humble opinion...especially as a "1st gen" tablet work suite...even for "Basic" revisions to .doc and .xls files. It's even got a basic set of templates for easy invoicing, scheduling, inventory, etc. I run my own business and have defaulted to a lot of my basic word processing and spreadsheet work on the iPad. I don't find it difficult at all.
For extensive word processing, I've upgraded to MS Office '11 (or is it '10) for Mac...and it's the best version yet...again, ON my Macs. However...since picking up version 1 of the iPad, I've started using the iWork suite as well on my Macs. Again, while I agree the latest version of MS Office is pretty awesome and a helluva lot more efficient, stable, and faster than any other version...I'm really starting to dig the iWork suite...which has EASY compatibility with MS Office...as long as your formatting in MS isn't super extensive. I'm not a super power user of Office, but I do use Word and Excel extensively. I should say...I have in the past. I've moved to about 70% of my Word Processing and Spreadsheet work to the iWork suite...both because it's really, REALLY good for what I need AND it works very well transitioning to and from my iPad...and Now, since last week...my iPhone! Pretty freakin' cool.
YMMV. It's not the best solution for extensive word processing or big time spreadsheet work...or for that matter, intensive slide show/PP production with Keynote. However, it DOES work. There are plenty of options as far as BT keyboards on the market (although the Apple one isn't the easiest to transport, it's excellent!). With that addition, and the speed boost of my iPad 2...and the EASY sharing of the mobile iWork suite production I do...I have found the iPad to be invaluable for different projects that I have to do, I can now do on the run, on the plane, or on site with my clients. It's perfect. Again, YMMV...and Please, PLEASE understand, I'm not vouching for Power Use of WProc or SSheet work on the iPad...nor presentation work. BUT, if you're not in to heavily formatting your work with proprietary MS Suite options, the transfers...in my case, between MS Office and iWork have been relatively decent.
That all said, I have to believe Microsoft is HARD at work developing an MS Office suite for the iPad. They do it for Mac and Macs only represent a 10-15% market share of total computer ownership. However...for tablet ownership, I believe Apple is still close to 75%...and that number may increase as these tablets from Android and Black Berry haven't proven to be mature...at least with their "App Options" at this point...so as we move in to the holiday season late this year...if these "issues" don't improve...iPad2 will see another sales boost at Christmas...again, IMHO. BUT...speaking from experience, I have owned a Xoom since release. I dig it, it's a great little experiment...but it is absolutely NOT the iPad. I may even pick up a playbook when they get email client, et al figured out later this summer...I like to give everything a fair shake and I'm fairly format neutral...however, I have completely switched from the Windows to the Mac environment at home and business use.
I think Microsoft is smart...they will sell their software, which is where their golden goose is...wherever IT sells itself. The iPad is a natural transition for them...even if they ARE going to introduce a couple of Windows tablets this fall/winter. Again...they do it for both Mac and PC....why not in the tablet world as well? IMHO, it's coming. But for now, for basic editing and writing, the iPad2 is excellent.
