I have a Surface Pro and owned a Thinkpad Tablet 2 for a while. No, you won't get tab reloading, but you will have all sorts of other, smaller delays, whether it's scrolling that isn't as smooth, the normal bevy of Windows updates, or the wait for the device to resume from sleep if it's been more than an hour or two since last use. Overall the ipad is a way better appliance. I really don't care about being able to run my office programs on a tablet when my ultra book is a better interface for that work. And the Windows Store is still a complete joke. You have an extremely few apps from big names, and then everything else is a hack put together by a 3rd rate developer with 2 star ratings that they really deserve.
Try to find a gmail app, or a browser other than IE that can actually integrate with your settings outside of that specific device.
Scrolling is nearly as smooth on my T100 as on my iPad 4 and my mini in my full Chrome browser, and ABSOLUTELY as smooth app-switching, starting new apps, etc. The trick for Chrome is their Canary Browser, it's their fully tablet optimized version, it's what's coming soon for regular Chrome, and it works great. It also runs in it's own profile so you can use production Chrome along side it. It blows ANY iOS browser out of the water cause it is a FULL desktop class browser, full extension support (AdBlock, HoverZoom, etc).
As for your wake up delays. I'm pretty sure the Haswell chipset in the Surface Pro's don't support connected standby. I've never had my system delay at all when I wake it. Open it up any time and it's instantly ready to go.
So I get full integration/syncing to my Google app ecosystem (Gmail, Docs, Calendar, Contacts, Drive, etc) as good as iOS or in some cases better (file management w/Drive for instance).
Windows updates? Yup. But any ultrabook has these too. I realize it's not an "appliance" but it is one device that for me can function as a PC AND an appliance. In iOS my most used apps are the following: Browser, Flipboard, Mail, Calendar, Reddit (reader), Kindle, Office type app, Photo app, Plex, Netflix, and a few games. Every one of these exist as good or better in a Windows format. All are touch optimized, fast and smooth - and they're only getting better and more will be coming.
"...Overall the ipad is a way better appliance. I really don't care about being able to run my office programs on a tablet when my ultra book is a better interface for that work..."
And on this comment let me say this: What if I told you my "appliance" becomes that "better interface" for that work when I snap on the keyboard and turn on my BT mouse? Hey I've loved using my iPads but you and I both know there are times while you're using it when you say "I'll deal with that later when I'm on my laptop/desktop" cause either you can't do "that" on an iPad or if you did it'd be convoluted and a PITA. Well for the first time in my tablet swiping days - I can now do THAT, whatever "that" is, whenever I want to.
Now is a Windows 8 device perfect? Of course not. Does it fit the needs of everybody? Nope. But for me, having the touch optimized consumption apps, and a full desktop of production apps (Photoshop runs great on this) when I need/want them means one device does everything I need. I'm not trying to convince/convert anybody, just pointing out that some of the earlier impressions of Win8 slates are no longer as relevant as it was 12 months ago.
Ask most iPad users if they'd like to be able to snap on a keyboard w/trackpd and hit an icon and drop into a fully functional OSX environment and I bet a few would want that, maybe not all, but some. I'm one of those right now, and I think it's going to get more and more popular as they refine and improve it, and the ecosystem.
Again, not sure yet if I'll move away from the iPad fully (nothing's going on Craigslist just yet) but I'm seeing a different perspective here, and it's interesting.
