I really, really enjoy my ipad. I spend so much less time on my desktop, and the ipad does so many things so very well (okay except for that flash thing... let's don't go there). It truly has changed the way I interact with the web, email, calendars, books, media/movies/tv.
I was though, very impressed with the Honeycomb demo at CES. Assuming all is as advertised, there were some very compelling features.
While I haven't been thrilled with widgets on my mac desktop, I can say that they seem useful to me on a tablet. There is plenty of data i regularly want to scan (weather, email and news, for example) the notion of that data being there at a glance seems useful on the tablet. I can't say why exactly it is not as compelling on my mac desktop, maybe because I have the same info on my igoogle home page, and my browser is always there on my desktop. Not so on my ipad. Also, Mossberg or someone such pointed out that the lock-screen could be showing something useful all the time and widgets seem a natural candidate there (although I am not sure Honeycomb supports a more "informative" lock screen running widgets.)
Tabbed browsing is an absolute must for me and hopefully it will show up soon on the ipad. I actually find Apple's scheme of page switching by shoving the old page into the background a little cumbersome to use. I can never really tell from the thumbnails and my bad eyesight which page is which... (okay, with a little looking i can tell). But tabs seem to make much more sense to me.
And finally, the geek (or ahem, computer professional) in me recognizes that the apple's multi-tasking seems a little clumsy (or sure, you can say it has more to do with simplicity... a true apple virtue). It seems to me that a more sophisticated scheme is needed to support things like widgets. I get the impression that apple's multi-tasking is sort of a fifo model with a limited number of slots. It almost feels like it was "hacked" on top of the original iOS. Yes, this is sort of a vague, hand-waving call. But I can believe the notion of an OS from scratch supporting multitasking better than having it "bolted on". Has Android had multitasking from the beginning?
That said, I can imagine that I will not give up my ipad in favor of anything else for the next few years. It has so radically changed the way I "compute" and it seems to me the Android features while nice would not be enough to make me switch. I can hope though, that the ipad incorporates a few of these features in the near future.
