Don't bother with official Foursquare official app. Instead, use 4th and Mayor, a much much better foursquare app that even foursquare themselves prefer this over their official app.

I have my hands on Lumia 800 and pretty honest, this is a sweet phone for sure. But I dunno if it can replace my souped up, 32GB modded- Dell Venue Pro as my main Windows Phone.

Still, good lord, I can spend hours just looking at the design of this phone. So sexy!

Told ya!
I mean, I am a geek, and the prospect of having a phone that I can customize the heck outta it is very compelling. But sure, over time, the urge to do so fade, and little by little I came to realization that I need a phone that always smooth, reliable, and keep me connected all the time. Thus, WP7 (and to some extent, my N9 running Meego) is the answer, at least for now. Its smooth, reliable (My Dell Venue Pro never hang or lag, and mind you, it is considered to be one of the most glitchy Windows Phone out there), and downright keeping my needs in check.

Enjoy the experience!
Hmm, I always thought that little-but-not-noticeable little pauses in 4th and Mayor was due to my Dell being the 1st gen windows phone. It seems like the app itself is the case. But hey, its still as impressive right?

For those who using Twitter, I'd suggests using Mehdoh for now. It provides one of the best twitter experience for the phone, plus the best part? Its free in the marketplace. Go for it!

TBH, I've been using the original Galaxy Tab since its launch, and trust me, in its stock form, its quite unbearable
Don't get me wrong, I perfectly understand its limitation and capabilities, which at least for me, its nothing to fuss at. Just a little bit of TLC, compromise and it shall handle all your needs admirably.

And for me, a mantra I always used if ppl ask me what Android phone should I recommend to them rings true all the time- Don't be a cheapskate. Go for the latest and greatest (Spec wise), and you will be fine. Well for most of the time. With ICS, I really felt that Galaxy S shall be the baseline spec that anyone should go for. Lesser than that, and you will be pulling your hair soon enuff. *Still remember my experience with HTC Wildfire. Brr, I almost throw the phone outta the window, something I never done to my gadgets before, even the uber craptastic N97

It only needs to go online to get the route data. For the maps itself, its downloadable. Once the route being established, no need for internet anymore.

No ill effect using higher output chargers? I'm afraid my gadgets will go boom after that

Yep. But I think the data downloaded is minimal, kinda like the data downloading needed for AGPS lock.
And once the route being established, you can go offline without any problem AFAIK.

Note that this only for Nokia Drive. Havent get enough quality time with Nokia Maps yet.

Unless you can get it very cheap, just don't bother with Arc S. Its good, I can attest to that. But IMO, its just too overpriced.

I'm using Dell Venue Pro, but I guess this rings true for every Windows Phone out there. No need to worry much about battery life IMHO. It'll last through the day.

Performance apps? Evernote, 3rd party Twitter, Whatsapp all available in the marketplace. I'd say all that you need is there. I've been using WP7 for several months now, and I can say most "performance" apps is available, or at least, its replacement. Plus, they look much better (Metro UI is sexy!)

So, in short, App wise, its good enough. And don't forget, its growing, at a very fast rate.

And don't forget, WP7 really smooth and stable! A far cry from the old WM6 days and Android.

I'd say based on what you said, WP7 is really suitable for you

I used Dropbox + Boxfiles for Dropbox personally.

And yes, Microsoft really need to do something regarding this issue
