4G: Bad coverage, crap battery life - but at least it's really expensive

some +s to LTE
"Then, remember that the LTE chips in this first generation of phones are immature and deplete the battery very rapidly, which for me is the clincher"
Second generation chipsets are already in most new phones. Most first generation phones were a combination of primarily data-only modems like the Qualcomm MDM 9x00 series combined with an application processor and other voice bits (together called fusion). Now we have the 28nm based 8x60 series. I am right now using a a galaxy note II LTE which admittedly also has large 3100mA battery (All corporate mail/personal mail/ NO FB and around 20 calls and 1/2 30-min conf-calls per-day) that normally lasts for a minimum of 3 days (in Germany on 800MHz spectrum with 10MHz bandwidth)
Couple of good things about LTE is that
- there is no cell-breathing ie., users at the edge of a cell don't get lopped off just because the number of people using the same cell in the center increase.
- The maximum up-link throughput in 3G HSPA+ as of today is 5.6Mbps [Cat 6] which is not comparable to 50Mbps (in 20MHz bandwidth and 25Mbps if the bandwidth is 10MHz assuming Cat-3 LTE). This is a boon when you use your phone as a hotspot. Note that there are higher categories in HSPA+ for unlink but you won't see deployment of these very soon.
- Latency -The experience is totally different between LTE and 3G. With my earlier 3G based phones is was very noticeable but with the LTE ones, the webpages just render as soon as the 'go' is pressed. This is most noticeable when using LTE tablets (the Acer transformer comes to mind)
Yes, there is no clean voice solution as of today but the CSFB solution works pretty well and I don't find it any different in experience when compared to my 3G phones. One thing that is really annoying with CSFB is that any data transfer is shot down in LTE if there is an incoming/outgoing call. SMS is handled via SGS, so that is not an issue.
It is not fair to compare HSPA DLDC (Downlink Dual-carrier ) to LTE because as the name suggests it does nothing to up-link. It is different when you talk about ULDC which is 3GPP Rel-10 feature and IMHO not see the light of the day until 2 years from now. I routinely get 25-30 Mbps in down-link and 10-12Mbps in the Uplink in LTE which is theoretically not possible with HSPA+ Cat 24/ UL cat-6. Byte-for-Byte LTE is MUCH more efficient.
One thing is true though, until a few operators start offering LTE, I would sit it out as well (if I were to be in the UK).

Google crams arsenal with 1,000 IBM patents

The only people who will benefit from this are lawyers. The ultimate looser are the users who would have to pay a higher price for devices which otherwise would be potentially less expensive. This might be good for Google, but if the whole patent crap is not sorted out, then we are ones who will be paying for all this nonsense.
